(Medical Xpress)—Cortical information is carried by axonal spike timing, which is also a key factor in synaptic plasticity. Spike timing, in turn, can be synchronized by cortical oscillations, thereby regulating cortical ...
Culminating an 8 year search, scientists at the RIKEN-MIT Center for Neural Circuit Genetics captured an elusive brain signal underlying memory transfer and, in doing so, pinpointed the first neural circuit for "oops" ? the ...

(Medical Xpress)—A recent neurological addressing one of the most fundamental issues in sleep rhythm generation study underscores an inconvenient truth—namely, that established scientific facts have and will continue ...
How information is processed and encoded in the brain is a central question in neuroscience, as it is essential for high cognitive function such as learning and memory. Theta-gamma oscillations are "brain waves" observed ...
