Lobes of the brain

The lobes of the brain were originally a purely anatomical classification, but have been shown also to be related to different brain functions. The telencephalon (cerebrum), the largest portion of the human brain, is divided into lobes, but so is the cerebellum. If not specified, the expression "lobes of the brain" refers to the telencephalon.

Terminologia Anatomica (1998) divides cerebrum into 6 lobes.^[1] (See individual articles for more information):

1. Frontal lobe—conscious thought; damage can result in mood changes, social differences, etc. The frontal lobes are the most uniquely human of all the brain structures.
2. Parietal lobe—plays important roles in integrating sensory information from various senses, and in the manipulation of objects; portions of the parietal lobe are involved with visuospatial processing
3. Occipital lobe—sense of sight; lesions can produce hallucinations
4. Temporal lobe—senses of smell and sound, as well as processing of complex stimuli like faces and scenes.
5. Limbic system—emotion, memory, emotional expression, resolve conflict from frustration. "Odors often trigger emotional reactions and memories" (Elaine & Katja, 2015).
6. Insula—"island inside" pain, taste, hunger, visceral functions, social emotions, time perception and awareness "connects to the cortex and the limbic systems" (Blanc et. al., 2014).
