Evoked activity in the mammalian cortex and the resulting behavioral responses exhibit a
large variability to repeated presentations of the same stimulus. This study examined …

The study of hominin brain evolution has focused largely on the neocortical expansion and
reorganization undergone by humans as inferred from the endocranial fossil record …

INTRODUCTION The establishment of neuronal circuits in the cerebral cortex of mammals is
an important developmental process extending over embryonic and postnatal periods, from …

Neurons in the rat primary auditory cortex (A1) generally cannot respond to tone sequences
faster than 12 pulses per second (pps). To test whether experience can modify this …

Conversion of new memories into a lasting form may involve the gradual refinement and
linking together of neural representations stored widely throughout neocortex. This …

Cortical neurons receive synaptic inputs from thousands of afferents that fire action
potentials at rates ranging from less than 1 hertz to more than 200 hertz. Both the number of …

The cerebral cortex is plastic and represents the world according to the significance of
sensory stimuli. However, cortical networks are embodied in complex circuits, including …

In the mammalian brain, sensory cortices exhibit plasticity during task learning, but how this
alters information transferred between connected cortical areas remains unknown. We found …

It has been proposed that the efficacy of neuronal connections is strengthened when there is
a persistent causal relationship between presynaptic and postsynaptic activity. Such activity …

In this report we describe how common brain networks within the medial frontal cortex (MFC)
facilitate adaptive behavioral control in rodents and humans. We demonstrate that after …
