Neurophysiological mechanisms of error monitoring in human and non-human primates
Performance monitoring is an important executive function that allows us to gain insight into
our own behaviour. This remarkable ability relies on the frontal cortex, and its impairment is …

Spatiotemporal transformations for gaze control
Sensorimotor transformations require spatiotemporal coordination of signals, that is, through
both time and space. For example, the gaze control system employs signals that are time‐…

Transition from target to gaze coding in primate frontal eye field during memory delay and memory–motor transformation
The frontal eye fields (FEFs) participate in both working memory and sensorimotor transformations
for saccades, but their role in integrating these functions through time remains unclear…

A minimal biophysical model of neocortical pyramidal cells: implications for frontal cortex microcircuitry and field potential generation
Ca 2+ spikes initiated in the distal trunk of layer 5 pyramidal cells (PCs) underlie nonlinear
dynamic changes in the gain of cellular response, critical for top-down control of cortical …

[HTML][HTML] Functional architecture of executive control and associated event-related potentials in macaques
The medial frontal cortex (MFC) enables executive control by monitoring relevant information
and using it to adapt behavior. In macaques performing a saccade countermanding (stop-…

Visual–motor transformations within frontal eye fields during head-unrestrained gaze shifts in the monkey
A fundamental question in sensorimotor control concerns the transformation of spatial signals
from the retina into eye and head motor commands required for accurate gaze shifts. Here, …

Spatial transformations between superior colliculus visual and motor response fields during head‐unrestrained gaze shifts
We previously reported that visuomotor activity in the superior colliculus ( SC ) – a key
midbrain structure for the generation of rapid eye movements – preferentially encodes target …

Cortical origin of theta error signals
A multi-scale approach elucidated the origin of the error-related-negativity (ERN), with its
associated theta-rhythm, and the post-error-positivity (Pe) in macaque supplementary eye field (…

[HTML][HTML] The influence of a memory delay on spatial coding in the superior colliculus: is visual always visual and motor always motor?
The memory-delay saccade task is often used to separate visual and motor responses in
oculomotor structures such as the superior colliculus (SC), with the assumption that these same …
