What makes up the temporal lobe




















It also helps you understand language, retain visual memories, and both process and remember emotions. Damage to this region of the brain can have global consequences for virtually every bodily function, since much of wha t we do depends on emotions and sensory input. Doctors sometimes refer to the temporal lobe as a pair of lobes, since the region crosses both left and right brain hemispheres, including one temporal lobe on each side.

Like the brain's other three lobes, the temporal lobe is located in the forebrain. Biologists believe this is the newest portion of the brain to have evolved, since it is only present in vertebrates. The temporal lobe is so named because of its proximity to the temples. It is positioned toward the base of the center of the cortex, just behind the temples.

Like all other brain regions, it is not a standalone organ. Instead, the temporal lobe interacts with and depends upon input from all other brain regions, as well as sensory input about the surrounding world.

In this way, the temporal lobe—and the brain it supports—is a dynamic organ. Rather than controlling the mind, it learns from the environment, creating a complex mind-body-environment interplay that constantly changes a person's subjective experiences.

Though every temporal lobe has a similar structure, the experiences produced in each person's temporal lobe are uniquely their own. As its position near the temples suggests, the temporal lobe plays a key role in auditory processing. This role includes perceiving sounds, assigning meaning to those sounds, and remembering sounds. Much of the auditory work of the temporal lobe is processed through the superior temporal gyrus, a temporal lobe structure that receives sound input directly from the ear.

Some of its other functions include:. As one of just four lobes in the brain, the temporal lobe is less a discrete organ, and more of a home to numerous other structures. Some of the most important structures in the temporal lobe include:. The temporal lobe is not a standalone organ. It directly interacts with other regions of the brain, and sends and receives signals to and from the spinal cord, allowing it to communicate with the entire body. Thus damage to the temporal lobe can affect functioning in far-flung organs, and damage to organs completely unrelated to the temporal lobe may impede its ability to receive, process, and respond to various cues.

Because the temporal lobe houses much of the limbic system, the temporal lobe is both heavily influenced by and influences a number of automatic bodily functions, including heart rate, arousal, anxiety, and similar states.

Over time, disruptions in these states can affect other bodily functions. For example, early childhood trauma predisposes some people to a chronic state of anxiety that keeps them in a state of fight-or-flight. This floods the body with hormones such as cortisol, and can lead to chronic inflammation, and even health problems such as infertility. Because the temporal lobe is involved in so many bodily functions, damage to the temporal lobe can be catastrophic. Learn more about schizophrenia here.

The temporal lobe is one of the four major lobes of the cortex. It is primarily responsible for interpreting sounds from the ears and plays a significant role in recognizing and using language. The temporal lobe also helps with object recognition and interacts with other structures to create new and long term memories. Dysfunction or damage in the temporal lobe may cause varying symptoms throughout the body, including memory impairments, changes in the emotional state, and hallucinations.
