Higher-order thalamic nuclei contribute to sensory processing via projections to primary and
higher cerebral cortical areas, but it is unknown which of their cortical and subcortical inputs …

We now know that sensory processing in cortex occurs not only via direct communication
between primary to secondary areas, but also via their parallel cortico-thalamo-cortical (ie …

Higher order thalamic neurons receive driving inputs from cortical layer 5 and project back to
the cortex, reflecting a transthalamic route for corticocortical communication. To determine …

Layer 6 (L6) is the sole purveyor of corticothalamic (CT) feedback to first-order thalamus and
also sends projections to higher-order thalamus, yet how it engages the full corticothalamic …

Knowledge of thalamocortical (TC) processing comes mainly from studying core thalamic
systems that project to middle layers of primary sensory cortices. However, most thalamic …

Neurons in thalamorecipient layers of sensory cortices integrate thalamocortical and
intracortical inputs. Although we know that their functional properties can arise from the …

Thalamocortical circuits are central to sensory and cognitive processing. Recent work
suggests that the thalamocortical inputs onto L4 and L6, the main input layers of neocortex …

Sensory processing involves information flow between neocortical areas, assumed to rely
on direct intracortical projections. However, cortical areas may also communicate indirectly …

Corticothalamic pathways, responsible for the top-down control of the thalamus, have a
canonical organization such that every cortical region sends output from both layer 6 (L6) …

Higher-order (HO) thalamic nuclei interact extensively and reciprocally with the cerebral
cortex. These corticothalamic (CT) interactions are thought to be important for sensation and …
