Nonlinear receptive field subunits in retinal ganglion cells are isolated and characterized by clustering spike-triggered stimuli, and validated on population responses to naturalistic and novel closed loop stimuli.
A characterization of LGN-V1 synaptic transmission properties demonstrates thalamocortical synapses in vivo are weak and unreliable, but biologically constrained models show they efficiently drive cortex.
In the visual system, three rules guide the thalamocortical connectivity of cortical fast-spike interneurons and are key to understand the potent and broadly tuned feed-forward inhibition that they generate.
Cerebellar Purkinje neurons use a multiplexed simple spike code combining synchrony/spike time and firing rate, with each component encoding distinct information about movements such as motion onset timing and kinematics.
In vivo recordings in unanesthetized zebrafish larvae show that Purkinje neurons have two stable membrane potential states and that climbing fiber inputs can toggle them to up states during motor episodes.
