Il ruolo del collicolo superiore nell'orientamento spaziale
This thesis was aimed at verifying the role of the superior colliculus (SC) in human spatial orienting. To do so, subjects performed two experimental tasks that have been shown to involve SC’s activation in animals, that is a multisensory integration task (Experiment 1 and 2) and a visual target …

Effetti dell'integrazione visuo-acustica in pazienti con disturbo di campo visivo
Human brain is provided with a flexible audio-visual system, which interprets and guides responses to external events according to spatial alignment, temporal synchronization and effectiveness of unimodal signals. The aim of the present thesis was to explore the possibility that such a system might …

Seizure prediction and control in epilepsy
The first part of my thesis presents an overview of the different approaches used in the past two decades in the attempt to forecast epileptic seizure on the basis of intracranial and scalp EEG. Past research could reveal some value of linear and nonlinear algorithms to detect EEG features changing …

Selectivity for Movement Direction in the Human Brain
In daily life, we frequently execute reaching movements, for example to be able to grasp our mobile phone. The processing of movement direction is fundamental to efficiently reach the target object. Many neurophysiological studies reported neuronal populations selective for movement direction in …

Motor Resonance meets Motor Performance: Neurocognitive investigations with transcranial magnetic stimulation
The classical mirror neuron theory of action understanding asserts that when we observe an action, the representations that are engaged for performing it, are automatically activated. In order to do gain information about the role of the simulation in action understanding a state dependent TMS …

The neurophysiology of internally-driven actions
Acting in the world in a way that matches our goals, overriding impulses, is one of the first abilities that we must learn while growing up. We often change the course of our actions because of external influences or because we simply “change our mind”. As John H. Patterson said, “Only fools and …

Neural mechanisms of attention to motion
Attention is thought to alter appearance by intensifying the sensory impression of the attended stimulus. Current debates are about how this increases might operate and what are the underlying neural mechanisms. Three mechanisms have been proposed to account the effect of attention: contrast gain, …

Decoding Auditory Motion Direction And Location In hMT+/V5 And Planum Temporale Of Sighted And Blind Individuals
The research presented in this thesis addresses the neural mechanisms of auditory motion processing and the impact of early visual deprivation on motion-responsive brain regions, by using functional magnetic resonance imaging. Visual motion, and in particular direction selectivity, is one of the …

Verbs and nouns in awake neurosurgery: needs and answers
Awake surgery is a surgical procedure applied to people with brain tumors. Patients are kept awake during surgery to perform language tasks during electrical stimulation of cortico-subcortical brain structures. When the application of electrical pulses to the brain repeatedly triggers errors, this …

Not the Pearls but the Thread: Using fNIRS Hyperscanning to Investigate Real-Life Social Interactions
… or more individuals. Since its introduction in 2002, this approach has represented a major methodological advance in social neuroscience, enabling researchers to directly investigate the neural mechanisms underlying active social exchange. Around the early 2010s, the use of functional …

The development of number processing and its relation to other parietal functions in early childhood
The project has explored the developmental trajectories of several cognitive functions related to different brain regions: parietal cortex (quantity manipulation, finger gnosis, visuo-spatial memory and grasping abilities) and occipito-temporal cortex (face and object processing), in order to …
