Neurons in the midbrain superior colliculus of free-flying echolocating bats represent 3D sensory space, and the depth tuning of single neurons is modulated by an animal's active sonar inspection of physical objects in its environment.
Spontaneous, irregular spiking in single cortical pyramidal neurons assembles as neuronal avalanches at the group level identifying a robust scale-invariant organization of resting activity in the awake state.
Recordings from the mouse brain as animals learn a lever pressing task reveal how the motor system optimizes skill learning by reducing variability in those aspects of task performance that are essential for achieving a goal.
As mice learn to associate events separated in time, neurons within the CA1 region of the hippocampus progressively reorganize their firing patterns, leading to a relay of cellular activity that bridges the two events.
During behavior, many neurons do not have classic trial-averaged responses to behaviorally relevant stimuli, but can still have activity and population dynamics related to stimulus and behavioral choice on single trials.
