Why Isn't the Head Direction System Necessary for Direction? Lessons From the Lateral Mammillary Nuclei.

abstract：:Every higher-order association cortex receives a variety of synaptic signals from different regions of the brain. How these cortical networks are capable of differentially responding to these various extrinsic synaptic inputs remains unclear. To address this issue, we studied how the basolateral amygdala (BLA) and the...
