Perception

Perception is the process by which the brain interprets sensory information from the environment and constructs a meaningful representation of the world. This process involves the integration of information from multiple sensory modalities, such as vision, hearing, touch, and others, and is mediated by a complex network of neural circuits in the brain.

One key brain region involved in perception is the primary sensory cortex, which is responsible for processing specific types of sensory information, such as visual information in the primary visual cortex or auditory information in the primary auditory cortex. These areas receive inputs from the sensory organs and transmit information to other brain regions for further processing.

Other brain regions involved in perception include the association areas, which are responsible for integrating information from multiple sensory modalities and constructing a coherent representation of the environment. This process involves the integration of information from multiple brain regions, including the primary sensory cortices, the thalamus, and other areas.

The prefrontal cortex is also involved in the higher-level processing of sensory information, such as attention, memory, and decision-making. It receives inputs from the primary sensory cortices and association areas and is involved in the selection and interpretation of sensory information.

Overall, the neural circuits involved in perception are complex and involve the integration of information from multiple brain regions and sensory modalities. Understanding these circuits is important for understanding how the brain processes and interprets sensory information and constructs a meaningful representation of the world (Gross, 2002) (Kosslyn, 2006).
