Neural correlates of category-specific knowledge

Article Abstract:

The capacity of the human brain to correlate objects and their names is stored as a distributed neural network, and the identification of different types of objects activates different parts of the brain. Mapping brain regions using positron emission tomography indicates that the ventral temporal lobes and Broca's area are activated when naming pictures of animals and tools. Naming animals selectively activates the left medial occipital lobe. Naming tools specifically activates a left promoter area, which is also activated when action words are formed.

Transient and sustained activity in a distributed neural system for human working memory

Article Abstract:

Functional magnetic resonance imaging technology used to identify dynamic measurements in brain neural activity shows three occipitotemporal areas in the ventral object vision pathway of the brain are mainly involved perceptual processing. The research also shows that three prefrontal areas of the brain, namely the posterior middle and inferior frontal gyri, the inferior frontal gyrus near the anterior end of the insula and the anterior middle frontal gyrus, are mainly involved in working memory functions.

Functional MRI evidence for adult motor cortex plasticity during motor skill learning

Article Abstract:

A transformation in the adult primary motor cortex (M1) may help in the learning and retention of complex motor skills. This was revealed by magnetic resonance imaging of local blood oxygenation level-dependent signals produced in the primary motor cortex during performance of these motor functions. Order of learning is irrelevant in the cortex activation.
