Genes alone don't determine how the cerebral cortex grows into separate functional areas. Input from the thalamus is also crucially required, a new study suggests.
Researchers discover a new phase of synaptic development. The finding could lead to a better understanding of how learning and memory occur.
UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that the entorhinal cortex behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.
