Understanding Consciousness

Consciousness can be defined as the state of being aware of and able to think about one's existence, sensations, and surroundings. It encompasses two major components: awareness and arousal. Awareness pertains to the recognition of environmental stimuli and internal states. At the same time, arousal refers to the physiological readiness to engage with these stimuli, which varies significantly between states like sleep and wakefulness.
Sleep, a crucial state, is characterized by reduced...

SECONDs Administration Guidelines: A Fast Tool to Assess Consciousness in Brain-injured Patients

These guidelines can be used for the administration of the Simplified Evaluation of CONsciousness Disorders (SECONDs), a short behavioral tool developed to diagnose brain-injured patients in time-constrained settings. This scale examines command-following, communication, visual pursuit, fixation, pain localization, oriented movements and arousal.

Infant Auditory Processing and Event-related Brain Oscillations06:34

Infant Auditory Processing and Event-related Brain Oscillations

High-density electroencephalography (dEEG) is being used increasingly to study brain development and plasticity in the early years of life. Here we present an application of sophisticated analysis techniques that builds on traditional EEG recording to understand the oscillatory dynamics of rapid auditory processing in the infant brain.

Conscious and Non-conscious Representations of Emotional Faces in Asperger's Syndrome08:31

Conscious and Non-conscious Representations of Emotional Faces in Asperger's Syndrome

An EEG experimental protocol is designed to clarify the interplay between conscious and non-conscious representations of emotional faces in patients with Asperger's syndrome. The technique suggests that patients with Asperger's syndrome have deficits in non-conscious representation of emotional faces, but have comparable performance in conscious representation with healthy...

Controlled Cortical Impact Model of Mouse Brain Injury with Therapeutic Transplantation of Human Induced Pluripotent Stem Cell-Derived Neural Cells

This protocol demonstrates methodologies for a mouse model of open-skull traumatic brain injury and transplantation of cultured human induced pluripotent stem cell-derived cells into the injury site. Behavioral and histologic tests of outcomes from these procedures are also described in...

Human Neural Organoids for Studying Brain Cancer and Neurodegenerative Diseases09:36

Human Neural Organoids for Studying Brain Cancer and Neurodegenerative Diseases

This study introduces and describes protocols to derive two specific human neural organoids as a relevant and accurate model for studying 1) human glioblastoma development within human neural organoids exclusively in humans and 2) neuron dopaminergic differentiation generating a three-dimensional...
