Inter-individual differences in fear extinction

In the scope of the research project 85/18 - Role of NT3/TrkC in the regulation of fear, supported by the BIAL Foundation, Mónica Santos and colleagues, using a behavioural model of fear extinction, assessed mice that successfully extinguish fear and those that fail. Inter-individual differences in the ability to extinguish fear have a dual outcome: first on setting the vulnerability to develop anxiety and fear-related disorders, and second on determining the effectiveness of exposure therapy towards patients in this group of disorders. Indeed, fear extinction mechanisms that support exposure therapy principles are often impaired in patients with fear-related disorders. The formation of fear memories and their extinction is dependent on synaptic plasticity events occurring at amygdalar fear and extinction microcircuits. Using the aforesaid model, the team identified a key role for the NT3-TrkC system in fear extinction, through modulation of amygdalar NMDAR composition and synaptic plasticity. This study validates the TrkC pathway as a potential therapeutic target for individuals with fear-related disorders and reveals that combining exposure therapies with drugs that enhance synaptic plasticity may represent a more effective and lasting way of treating anxiety disorders. To know more read the paper The amygdala NT3-TrkC pathway underlies inter-individual differences in fear extinction and related synaptic plasticity published in the journal Molecular Psychiatry.

The oxytocin’s (OT) role in human cognition

In the scope of the research project 292/16 - Oxytocin: On the psychophysiology of trust and cooperation, supported by the BIAL Foundation, the research team led by Diana Prata conducted a double-blind, between-subjects, placebo-controlled pharmaco-EEG aimed to test whether intranasal OT (inOT) affects the neural processing time-course of salience attribution processing of social stimuli (expressing fearfulness) and non-social stimuli (fruits) made relevant via monetary reinforcement. The main highlights of the study were: intranasal OT affected early ERPs regardless of (fearful) social or reward contexts; OT’s role in fear-related early salience attribution, may be social/reward-independent; the partially support the tri-phasic model of OT, which posits OT enhances salience attribution in an early perception stage regardless of socialness. To know more, read the paper Oxytocin modulates neural activity during early perceptual salience attribution published in the journal Psychoneuroendocrinology.

The perception of visual motion

Everyday interactions with the environment require a correct estimation of both self- and object- motion velocities. Perception of object-motion speed is essential to approach or avoid them properly. In many circumstances, object-motion perception is complicated by concomitant self-motion. One of the main challenges for the visual system is to determine the source of the movement that generates the flow pattern: self-motion, object-motion, or their combination. Thus, the research team led by Valentina Sulpizio aimed to establish (1) the sensitivity of several motion-related cortical regions (egomotion regions) to different visually induced motion conditions, including both self- and object-displacements and a combination of them; and (2) whether the activity of these regions was affected by the velocity of both self- and object-motion, thus providing new insight into their role in discriminating between different self- and object-motion velocities. A differentiated profile emerged among the egomotion regions (cingulate sulcus visual area, posterior cingulate sulcus area, posterior insular cortex [PIC], V6+, V3A, IPSmot/VIP, and MT+) during a visual motion stimulation including self- and object-displacements and a combination of them. All the egomotion regions (except area PIC) responded to all the possible combinations of self- and object-motion and were further modulated by the self-motion velocity. Interestingly, only MT+, V6+, and V3A were further modulated by object-motion velocities, hence reflecting their possible role in discriminating between distinct velocities of self- and object-motion. These findings are detailed in the paper Neural sensitivity to translational self- and object-motion velocities published in the journal Human Brain Mapping, in the scope the research project 24/20 - World-relative object motion: How the brain detects object motion while we are moving, supported by the BIAL Foundation.

The influence of environmental spatial references on vestibular self-motion

While navigating through the surroundings, we constantly rely on inertial vestibular signals for self-motion along with visual and acoustic spatial references from the environment. However, the interaction between inertial cues and environmental spatial references is not yet fully understood. To address this, Elisa Ferrè, principal investigator of research project 41/20 - Luminous dancing fairies in weightlessness: How gravity shapes conscious experiences, supported by the BIAL Foundation, aimed to investigate the influence of environmental visual and auditory spatial references on vestibular self-motion. A Vestibular Self-Motion Detection Task was administered to twenty-six healthy participants in which they were asked to detect brief self-motion sensations induced by low-intensity Galvanic Vestibular Stimulation (GVS). Participants performed this task either with or without a visual or acoustic spatial reference positioned directly in front of them. Results showed that the visual spatial reference increased sensitivity to detect vestibular self-motion. Conversely, the acoustic spatial reference did not influence self-motion sensitivity. This seems to suggest a specific interaction between visual and vestibular systems in self-motion perception. More information available in the paper Spatial Sensory References for Vestibular Self-Motion Perception published in the journal Multisensory Research.

The interplay between rhythm and motor skills

São Luís Castro, principal investigator of the research project 304/14 - The impact of music training on reading and mathematical abilities of normal and reading disabled children: a behavioral and neuroimaging longitudinal study, supported by the BIAL Foundation, aimed to study the interplay between rhythm and motor skills in the context of music training, at behavioral and brain levels. In a longitudinal study with children, it was explored whether the ability to perceive or reproduce rhythm (predisposition) modulates the motor improvements associated with music training, and identified brain regions implicated in the putative links between rhythm and motor learning. Fifty-seven 8-year-old children participated in a longitudinal study where they completed rhythm and motor tasks, as well as structural MRI scans before and after a 6-month music training (n= 21) or a sports program (n= 18), or no specific training (passive control group, n = 18). It was found that music training improved motor performance (and also rhythm), and that the magnitude of the improvement depended on the ability to perceive rhythm before training (i.e., better rhythm predisposition, more significant improvements). Music training also induced a loss of gray matter volume in the left cerebellum and fusiform gyrus, and volume loss correlated with higher motor gains. No such effects were found in the sports and control groups. These findings are presented in the paper Individual differences in rhythm perception modulate music‑related motor learning: a neurobehavioral training study with children published in Scientific Reports.

How do blind individuals perceive emotional authenticity?

In the scope of the research project 148/18 - Voice perception in the visually deprived brain: Behavioral and electrophysiological insights, supported by the BIAL Foundation, the research team, led by Tatiana Conde, aimed to explore how blind individuals perceive emotional authenticity. Combining behavioural and ERP measures it was investigated authenticity perception in laughter and crying in individuals early-blind (n = 17) late-blind (n = 17), and sighted control participants (n = 51). Behaviourally, early-blind and sighted participants performed similarly well in emotional authenticity perception, but the late-blind group performed worse than sighted controls. In brain responses, all groups were sensitive to laughter authenticity at the P2 stage, and to crying authenticity at the early LPP stage. Nevertheless, only early-blind participants were sensitive to crying authenticity at the N1 and middle LPP stages, and to laughter authenticity at the early LPP stage. Furthermore, early-blind and sighted participants were more sensitive than late-blind ones to crying authenticity at the P2 and late LPP stages. Altogether, these findings suggest that prolonged visual deprivation with late-onset impairs the processing of emotional authenticity. For more information read the paper Blindness influences emotional authenticity perception in voices: Behavioral and ERP evidence published in the journal Cortex.

The quest of physiological markers for the experience of pain

Researcher: Elia Valentini - Department of Psychology & Centre for Brain Science, University of Essex Summary: The aim of this project is to improve measurement of the human experience of pain by investigating a combination of psychophysical and physiological responses during mild noxious stimulation. More specifically, we want to investigate how sensitive and specific to pain the brain oscillatory responses are. We use EEG as the main technique, but we are keen to collaborate with neuroscientists using fMRI, autonomic measures and brain stimulation as well as with computational neuroscientists. A clinical collaborator would also be very much welcome.

EEG investigation of hypnosis and decision-making

Researcher: Rinaldo Livio Perri - University Niccolò Cusano Rome, Italy Summary: I work in the field of hypnosis and cognitive neuroscience. In particular, I adopt the event-related potentials (ERPs) to investigate the effect of the hypnotic suggestions on sensory processing and cognitive performance. I am an expert in decision-making and proactive brain processes before the stimulus administration (e.g., the perceptual, prefrontal and premotor readiness during the expectancy stage). I could help colleagues to properly analyze the ERP signal in the pre-stimulus stage of processing. Also, I would be happy to share my EEG data for re-analyzing them in the frequency domain (e.g., wavelet or coherence analysis in the hypnosis research). Feel free to contact me for any question!
