Categorization of behavioral sequences in the prefrontal cortex

Article Abstract:

A study was conducted to show that cells in the lateral prefrontal cortex of primates selectively exhibit activity for a specific category of behavioral sequences and that category of behaviors embodied by different types of movement sequences are represented in prefrontal cells during the process of planning. This cellular activity implies the generation of neural representations capable of storing structural event complexes at an abstract level.

Semantic combinations in primate calls

Article Abstract:

Study is conducted to show that free-ranging putty-nosed monkeys combine two vocalizations into different call sequences that are linked to specific external events, such as the presence of a predator and the imminent movement of the group. The findings indicate that non-human primates could combine call into higher-order sequences that have a particular meaning.

Integration of target and body-part information in the premotor cortex when planning action

Article Abstract:

The premotor area of the cerebral cortex of primates is probably involved in the integration of target and body-part information. A new study shows that neurones in the lateral sector of the dorsal premotor cortex gather information about the target and body-part to plan an action.
