Male alcohol consumption before conception was linked to significant deficits in their offspring's brain development, specifically within the neocortex. For mothers-to-be who drink alcohol, the negative outcomes of prenatal alcohol exposure on fetal brain development can be reduced with choline supplementation.
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.
Boundary contraction may be as common as boundary extension, and whether something appears zoomed in or out depends on the properties of the image.

Using artificial intelligence and brain-computer interface technology, researchers reconstructed English words from neural signals recorded from the brains of non-human primates.
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.
Scientists generated statistical instances of the micro-connectome, containing over 10 million neurons. The model spans five orders of magnitude and contains 88 billion synaptic connections.
Machine learning is unable to tell the difference in brain activity between a lab-grown mini-brain and that of a preterm infant who has reached full-term.
Functional connectivity problems associated with temporal lobe epilepsy appear to improve after surgery.
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.
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.
