This post is a list of major systems in the human brain. There are 11 systems listed below alphabetically. License: CC BY-SA 3.0
1. Auditory system (hearing)
"The auditory system is the sensory system for the sense of hearing. It includes both the sensory organs (the ears) and the auditory parts of the sensory system." (Wikipedia: Auditory system, 7.6.21 UTC 03:58)
2. Central nervous system (brain and spinal cord)
"The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because it integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric animals..." (Wikipedia: Central nervous system, 8.9.21 UT 07:04)

3. Endocrine system (hormones)
"The endocrine system is a messenger system comprising feedback loops of the hormones release by internal glands of an organism directly into the circulatory system, regulating distant target organs." (Wikipedia: Endocrine system, 7.30.21 UTC 17:33)
4. Gustatory system (taste)
"The gustatory system or sense of taste is the sensory system that is partially responsible for the perception of taste (flavor)." (Wikipedia: Taste, 8.2.21 UTC 05:20)
5. Limbic system (emotion, behavior, motivation, memory, smell)
"[The limbic system] supports a variety of functions including emotion, behavior, motivation, long-term memory and olfaction. Emotional life is largely housed in the limbic system." (Wikipedia: Limbic system, 8.3.21 UTC 09:03)
6. Olfactory system (smell)
"The olfactory system, or sense of smell, is the sensory system used for smelling (olfaction)." (Wikipedia: Olfactory system, 8.3.21 UTC 00:32)
7. Peripheral nervous system (nerves outside brain and spinal cord)
"The peripheral nervous system consists of the nerves and ganglia outside the brain and the spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the rain and spinal cord and the rest of the body." (Wikipedia: Peripheral nervous system, 7.19.21 UTC 11:57)
8. Reward system (motivation)
"The reward system is a group of neural structures responsible for incentive salience (i.e. motivation and 'wanting', desire, or craving for a reward), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones which involve pleasure as a core component." (Wikipedia: Reward System, 8.14.21 UTC 07:28)
9. Somatosensory system (touch)
"Somatic senses... include the sense of touch, proprioception (sense of position and movement), and (depending on usage) haptic perception." (Wikipedia: Somatosensory system, 6.3.21 UTC 13:18)
10. Ventricular system (cerebrospinal fluid)
"The ventricles are filled with cerebrospinal fluid (CSF) which bathes and cushions the brain and spinal cord within their bony confines." (Wikipedia: Ventricular system, 5.6.21 UTC 13:13)
11. Visual system (vision)
"The visual system comprises the sensory organ (the eye) and the part of the central nervous system which gives organisms the ability to process visual detail as sight, as well as enabling the formation of several non-image photo response functions." (Wikipedia: Visual system, 8.10.21 UTC 09:10)
