How a Gene Mutation Causes Higher Intelligence – Neuroscience News

Summary: A rare genetic mutation that causes blindness also appears to be associated with above-average intelligence, a new study reports. Source: University of Leipzig Synapses are the contact points in the brain via which nerve cells ‘talk’ to each other. Disturbances in this communication lead to diseases of the nervous system, since altered synaptic proteins, …
