People with autism perceive drastic illusory changes for repetitive verbal stimuli

Do Fish Perceive Illusory Motion?

Motion illusion refers to a perception of motion that is absent or different in the physical stimulus. These illusions are a powerful non-invasive tool for understanding the neurobiology of vision because they tell us, indirectly, how we process motion. There is general agreement in ascribing motion illusion to higher-level processing in the visual cortex, but debate remains about the exact rol...

Can adolescents with autism perceive emotional prosody?

Past findings on the perception of emotional prosody by individuals with Autism Spectrum Disorder (ASD) have been incongruent, and a main reason is the lack of clarity about the contributions of specific acoustic features to emotion perception. In this study we test the perception of emotional prosody by adolescents with ASD using a recently developed prosody control method based on a bio-infor...

Regional gray matter volumetric changes in autism associated with social and repetitive behavior symptoms

BACKGROUND Although differences in brain anatomy in autism have been difficult to replicate using manual tracing methods, automated whole brain analyses have begun to find consistent differences in regions of the brain associated with the social cognitive processes that are often impaired in autism. We attempted to replicate these whole brain studies and to correlate regional volume changes wit...

Illusory Sensation of Movement Induced by Repetitive Transcranial Magnetic Stimulation

Human movement sense relies on both somatosensory feedback and on knowledge of the motor commands used to produce the movement. We have induced a movement illusion using repetitive transcranial magnetic stimulation over primary motor cortex and dorsal premotor cortex in the absence of limb movement and its associated somatosensory feedback. Afferent and efferent neural signalling was abolished ...
