The dentate gyrus (DG) of the mammalian hippocampus is hypothesized to mediate pattern
separation—the formation of distinct and orthogonal representations of mnemonic …

Learning-related changes in brain activity are thought to underlie adaptive behaviours,. For
instance, the learning of a reward site by rodents requires the development of an over …

Attention can be focused volitionally by “top-down” signals derived from task demands and
automatically by “bottom-up” signals from salient stimuli. The frontal and parietal cortices are …

Perceptual decisions are based on the activity of sensory cortical neurons, but how
organisms learn to transform this activity into appropriate actions remains unknown …

Recent data on learning-related changes in animal and human auditory cortex indicate
functions beyond mere stimulus representation and simple recognition memory for stimuli …

A central tenet in brain research is that early sensory cortex is modality specific, and, only in
exceptional cases, such as deaf and blind subjects or professional musicians, is influenced …

Learning and memory arise through activity-dependent modifications of neural circuits.
Although the activity dependence of synaptic efficacy has been studied extensively, less is …

The auditory system, like the visual and somatosensory systems, contains topographic maps
in its central neural pathways. These maps can be modified by sensory deprivation, injury …

When new learning occurs against the background of established prior knowledge, relevant
new information can be assimilated into a schema and thereby expand the knowledge base …

Learning induces neuronal receptive field (RF) plasticity in primary auditory cortex. This
plasticity constitutes physiological memory as it is associative, highly specific, discriminative …
