Why those on the autism spectrum are often hypersensitive to light and noise

Mice lacking the autism-associated SHANK3 gene were more sensitive to sensation, including touch. The mice also had overactive excitatory neurons in the somatosensory cortex, which may account for sensory hypersensitivity.

Why images may appear closer, or farther, than they actually are

Boundary contraction may be as common as boundary extension, and whether something appears zoomed in or out depends on the properties of the image.

Research sheds new light on how the brain forms and recalls memories

During memory formation, the directional coupling between the neocortex and hippocampus alters. Decreased power in brain oscillations in the neocortex preceded and predicted increased power in the hippocampus. The reverse occurs during memory retrieval.

Brain changes in autism traced to specific cell types

Studying brain tissue samples from people with ASD revealed a common set of alterations in genes associated with synaptic communication between neurons. The changes were identified mainly in neurons in the uppermost layers of the neocortex.

Blue Brain solves a century-old neuroscience problem

A mathematical algorithm developed by the Blue Brain Project can objectively classify different shapes of neurons in the brain. The algorithm has already helped researchers objectively identify 17 types of pyramidal neurons in the somatosensory cortex of a rat.

Brain Wave Stimulation May Improve Alzheimer’s Symptoms

Multisensory gamma wave stimulation improves recognition and spatial memory, in addition to reducing amyloid in the auditory cortex and hippocampal CA1 areas of mice. Findings suggest such sensory stimulation boosts hippocampal function and reduces Alzheimer's linked pathologies throughout the neocortex.
