Sparse coding of sensory inputs
Several theoretical, computational, and experimental studies suggest that neurons encode
sensory information using a small number of active neurons at any given point in time. This …

Reliability of cortical activity during natural stimulation
Response reliability is complementary to more conventional measurements of response
amplitudes, and can reveal phenomena that response amplitudes do not. Here we review …

Stimulus-dependent representational drift in primary visual cortex
TD Marks, MJ Goard - Nature communications, 2021 - nature.com
To produce consistent sensory perception, neurons must maintain stable representations of
sensory input. However, neurons in many regions exhibit progressive drift across days …

Dendritic excitability and synaptic plasticity
Most synaptic inputs are made onto the dendritic tree. Recent work has shown that dendrites
play an active role in transforming synaptic input into neuronal output and in defining the …

Do we know what the early visual system does?
We can claim that we know what the visual system does once we can predict neural
responses to arbitrary stimuli, including those seen in nature. In the early visual system …

Sparse representation of sounds in the unanesthetized auditory cortex
How do neuronal populations in the auditory cortex represent acoustic stimuli? Although
sound-evoked neural responses in the anesthetized auditory cortex are mainly transient …

Natural images are reliably represented by sparse and variable populations of neurons in visual cortex
T Yoshida, K Ohki - Nature communications, 2020 - nature.com
Natural scenes sparsely activate neurons in the primary visual cortex (V1). However, how
sparsely active neurons reliably represent complex natural images and how the information …

Small modulation of ongoing cortical dynamics by sensory input during natural vision
J Fiser, C Chiu, M Weliky - Nature, 2004 - nature.com
During vision, it is believed that neural activity in the primary visual cortex is predominantly
driven by sensory input from the environment. However, visual cortical neurons respond to …
