Visual functions of the thalamus
The thalamus is the heavily interconnected partner of the neocortex. All areas of the
neocortex receive afferent input from and send efferent projections to specific thalamic …

Removal of perineuronal nets unlocks juvenile plasticity through network mechanisms of decreased inhibition and increased gamma activity
KK Lensjø, ME Lepperød, G Dick… - Journal of …, 2017 - Soc Neuroscience
Perineuronal nets (PNNs) are extracellular matrix structures mainly enwrapping
parvalbumin-expressing inhibitory neurons. The assembly of PNNs coincides with the end of …

[HTML][HTML] Wireless neurosensor for full-spectrum electrophysiology recordings during free behavior
Brain recordings in large animal models and humans typically rely on a tethered connection,
which has restricted the spectrum of accessible experimental and clinical applications. To …

Enhanced spatial resolution during locomotion and heightened attention in mouse primary visual cortex
We do not fully understand how behavioral state modulates the processing and transmission
of sensory signals. Here, we studied the cortical representation of the retinal image in mice …

[HTML][HTML] Epidermal growth factor signaling promotes sleep through a combined series and parallel neural circuit
Sleep requires sleep-active neurons that depolarize to inhibit wake circuits. Sleep-active
neurons are under the control of homeostatic mechanisms that determine sleep need …

The divisive normalization model of V1 neurons: a comprehensive comparison of physiological data and model predictions
The physiological responses of simple and complex cells in the primary visual cortex (V1)
have been studied extensively and modeled at different levels. At the functional level, the …

Cortical balance of excitation and inhibition is regulated by the rate of synaptic activity
Cortical activity is determined by the balance between excitation and inhibition. To examine
how shifts in brain activity affect this balance, we recorded spontaneous excitatory and …

Axonal conduction delays, brain state, and corticogeniculate communication
Thalamocortical conduction times are short, but layer 6 corticothalamic axons display an
enormous range of conduction times, some exceeding 40–50 ms. Here, we investigate (1) …

Brain state-dependent modulation of thalamic visual processing by cortico-thalamic feedback
K Reinhold, A Resulaj, M Scanziani - Journal of Neuroscience, 2023 - Soc Neuroscience
The behavioral state of a mammal impacts how the brain responds to visual stimuli as early
as in the dorsolateral geniculate nucleus of the thalamus (dLGN), the primary relay of visual …

Three rules govern thalamocortical connectivity of fast-spike inhibitory interneurons in the visual cortex
Some cortical neurons receive highly selective thalamocortical (TC) input, but others do not.
Here, we examine connectivity of single thalamic neurons (lateral geniculate nucleus, LGN) …
