Explain the contribution of cholinergic system in controlling different levels of activities.

The cholinergic system contributes to brain activities related to attention and higher-order cognitive processes.

Explanation:

The cholinergic system fundamental for cognitive functions, such as memory, selective attention, and even emotional processes. These memory processes require cholinergic activity over brain parts linked to memory retention and consolidation, including the cerebral cortex, and the amygdala.

While damage in the central cholinergic neurons weakens memory, the intensification of cholinergic synapses enhances cognitive processes.
