Not so spontaneous: Multi-dimensional representations of behaviors and context in sensory areas
Sensory areas are spontaneously active in the absence of sensory stimuli. This
spontaneous activity has long been studied; however, its functional role remains largely …

Hippocampal spatial view cells for memory and navigation, and their underlying connectivity in humans
ET Rolls - Hippocampus, 2023 - Wiley Online Library
Hippocampal and parahippocampal gyrus spatial view neurons in primates respond to the
spatial location being looked at. The representation is allocentric, in that the responses are …

Modality-specific tracking of attention and sensory statistics in the human electrophysiological spectral exponent
A hallmark of electrophysiological brain activity is its 1/f-like spectrum–power decreases with
increasing frequency. The steepness of this 'roll-off'is approximated by the spectral …

Learning and attention reveal a general relationship between population activity and behavior
Prior studies have demonstrated that correlated variability changes with cognitive processes
that improve perceptual performance. We tested whether correlated variability covaries with …

Priority coding in the visual system
Although we are continuously bombarded with visual input, only a fraction of incoming visual
events is perceived, remembered or acted on. The neural underpinnings of various forms of …

The dynamical regime of sensory cortex: stable dynamics around a single stimulus-tuned attractor account for patterns of noise variability
Correlated variability in cortical activity is ubiquitously quenched following stimulus onset, in
a stimulus-dependent manner. These modulations have been attributed to circuit dynamics …

Behavior needs neural variability
Human and non-human animal behavior is highly malleable and adapts successfully to
internal and external demands. Such behavioral success stands in striking contrast to the …

Circuit models of low-dimensional shared variability in cortical networks
Trial-to-trial variability is a reflection of the circuitry and cellular physiology that make up a
neuronal network. A pervasive yet puzzling feature of cortical circuits is that despite their …

Different computations underlie overt presaccadic and covert spatial attention
Perception and action are tightly coupled: visual responses at the saccade target are
enhanced right before saccade onset. This phenomenon, presaccadic attention, is a form of …

Learning and attention increase visual response selectivity through distinct mechanisms
Selectivity of cortical neurons for sensory stimuli can increase across days as animals learn
their behavioral relevance and across seconds when animals switch attention. While both …
