Journal ArticleDOI
Canonical Microcircuits for Predictive Coding
André M. Bastos,William Martin Usrey,Rick A. Adams,George R. Mangun,Pascal Fries,Pascal Fries,Karl J. Friston +6 more
TL;DR: This analysis discloses a remarkable correspondence between the microcircuitry of the cortical column and the connectivity implied by predictive coding and provides some intuitive insights into the functional asymmetries between feedforward and feedback connections and the characteristic frequencies over which they operate.
Journal ArticleDOI
The sublaminar organization of corticogeniculate neurons in layer 6 of macaque striate cortex
TL;DR: It is found that layer 6 of macaque striate cortex consists of three distinct sublayers only two of which are the source of descending projections to the LGN: an upper tier that projects exclusively to the parvocellular layers and a lowertier that projects to both magnocellular and parvo cellular layers.
Journal ArticleDOI
Simultaneous Recordings from the Primary Visual Cortex and Lateral Geniculate Nucleus Reveal Rhythmic Interactions and a Cortical Source for Gamma-Band Oscillations
TL;DR: Although the LGN and V1 display functional interactions in the lower frequency bands, gamma-band activity in the alert monkey is largely an emergent property of cortex, and an analysis of oscillatory phase synchronization identified synchronization in the alpha (8–14 Hz) and beta (15–30 Hz) frequency bands.
Journal ArticleDOI
A Fast, Reciprocal Pathway between the Lateral Geniculate Nucleus and Visual Cortex in the Macaque Monkey
TL;DR: A subclass of corticogeniculate neurons that receives direct, suprathreshold input from the LGN that is similar in latency to that directed to other recipient neurons is identified, indicating that visual signals can rapidly travel from the periphery to the cortex and back to the L GN.
Journal ArticleDOI
Spike Timing and Information Transmission at Retinogeniculate Synapses
TL;DR: It is shown that relayed spikes are more likely than nonrelayed spikes to be evoked by stimuli that match the receptive fields of the recorded cells and that an interspike interval-based mechanism contributes to the process.
