Chandelier cells unveil human cognition

What is it that distinguishes humans from other mammals? The answer to this question lies in the neocortex – the part of the brain responsible for sensory perceptions, conscious thought, and language. Humans have a considerably larger neocortex than other mammals, making it an ideal subject for the research of higher cognition. In this month's issue of PLoS Biology, authors Tamas, et al, reveal new insights into the mysteries of neocortex organization and function.
