    Study Notes

    Human Brain Overview

    • Humans have one brain, composed of approximately 86 billion neurons.
    • A unique feature of the human brain is its high degree of complexity and connectivity, particularly in the cerebral cortex, which is associated with advanced cognitive functions.

    Primary Function

    • The primary function of the human brain includes the regulation of bodily functions, processing sensory information, and enabling cognitive activities such as thinking, memory, and language.

    Comparison to Reptilian Brain

    • The human brain differs from the reptilian brain in size, structure, and functionality. Humans possess a larger cerebral cortex and a more developed prefrontal cortex, facilitating reasoning and decision-making.
    • Reptilian brains focus more on basic survival instincts and reflexive actions due to their simpler structure.

    Brain Function Description

    • Brain function can be accurately described as the integration and processing of information, enabling responses to environmental stimuli and management of bodily systems.
