temporal lobe

Examples of temporal lobe in the following topics:

• Cerebral Lobes

  • The cortex is divided into four main lobes: frontal, parietal, occipital, temporal.
  • The frontal lobe is an area in the mammalian brain located at the front of each cerebral hemisphere and positioned anterior to (in front of) the parietal lobe and superior and anterior to the temporal lobes.
  • The temporal lobe is involved in primary auditory perception such as hearing and holds the primary auditory cortex.
  • The superior temporal gyrus includes an area where auditory signals from the ear first reach the cerebral cortex and are processed by the primary auditory cortex in the left temporal lobe.
  • Distinguish between the frontal, temporal, parietal, and occipital lobes of the cerebral cortex

• Cerebral Hemispheres and Lobes of the Brain

  • The brain is separated into four lobes: the frontal, temporal, occipital, and parietal lobes.
  • The temporal lobe is associated with the retention of short- and long-term memories.
  • The temporal lobe contains the hippocampus, which is the memory center of the brain.
  • One specific portion of the temporal lobe, Wernicke's area, plays a key role in speech comprehension.
  • The Broca's area is at the back of the frontal lobe, and the Wernicke's area is roughly where the temporal lobe and parietal lobe meet.

• The Limbic System

  • The limbic system is a complex set of structures found on the central underside of the cerebrum, comprising inner sections of the temporal lobes and the bottom of the frontal lobe.
  • The amygdala is a small almond-shaped structure; there is one located in each of the left and right temporal lobes.
  • The hippocampus is found deep in the temporal lobe, and is shaped like a seahorse.
  • rule-based habit learning (e.g., initiating, stopping, monitoring, temporal sequencing, and maintaining the appropriate movement);
  • This image shows the horned hippocampus deep within the temporal lobe.

• Neural Correlates of Memory Storage

  • Recent functional-magnetic-resonance-imaging (fMRI) studies detected working memory signals in the medial temporal lobe and the prefrontal cortex.
  • The temporal and occipital lobes are associated with sensation and are thus involved in sensory memory.
  • Short-term memory is supported by brief patterns of neural communication that are dependent on regions of the prefrontal cortex, frontal lobe, and parietal lobe.
  • The processes of consolidating and storing long-term memories have been particularly associated with the prefrontal cortex, cerebrum, frontal lobe, and medial temporal lobe.
  • The temporal lobe is important for sensory memory, while the frontal lobe is associated with both short- and long-term memory.

• The Brain

  • Anatomists conventionally divide each hemisphere into four lobes: the frontal (control of specialized motor control, learning, planning, and speech), parietal (control of somatic sensory functions), occipital (control of vision), and temporal lobes (control of hearing and some speech).
  • The division into lobes does not actually arise from the structure of the cortex itself.
  • Found deep in the temporal lobe, the seahorse-shaped hippocampus is responsible for memory.
  • The amygdala is a small, almond-shaped structure deep inside the anteroinferior region of the temporal lobe.
  • Demonstration of brain regions, including the four lobes and internal structures.

• Cerebral Cortex

  • The cortex is divided into four different lobes (the parietal, occipital, temporal, and frontal lobes), each with a different specific function.
  • One notable sulcus is the central sulcus, or the wrinkle dividing the parietal lobe from the frontal lobe.
  • A diagram of the brain identifying the different lobes by color.
  • Counterclockwise from bottom: It contains the parietal lobe (green), the occipital lobe (red), the temporal lobe (yellow), and the frontal lobe (blue).

• Brain: Cerebral Cortex and Brain Lobes

  • The cerebral cortex of the brain is divided into four lobes responsible for distinct functions: frontal, parietal, temporal, and occipital.
  • Each hemisphere of the mammalian cerebral cortex can be broken down into four functionally- and spatially-defined lobes: frontal, parietal, temporal, and occipital .
  • The parietal lobe is located at the top of the brain.
  • The temporal lobe is located at the base of the brain by the ears.
  • The human cerebral cortex includes the frontal, parietal, temporal, and occipital lobes, each of which is involved in a different higher function.

• Human Language and the Brain

  • Broca's area, located in the frontal lobe of the brain, is linked to speech production, and recent studies have shown that it also plays a significant role in language comprehension.
  • The primary auditory cortex, located in the temporal lobe and connected to the auditory system, is organized so that it responds to neighboring frequencies in the other cells of the cortex.
  • The angular gyrus, located in the parietal lobe of the brain, is responsible for several language processes, including number processing, spatial recognition and attention.
  • The areas of the brain necessary for processing language: Broca's area, Wernicke's area, the primary motor cortex, the posterior middle temporal gyrus, and the middle and posterior superior temporal gyrus.

• Overview of the Cerebrum

  • Each hemisphere of the mammalian cerebral cortex can be broken down into four functionally and spatially defined lobes: frontal, parietal, temporal, and occipital.
  • The temporal lobe is located at the base of the brain by the ears.
  • The occipital lobe is located at the back of the brain.
  • Motor portions of language are attributed to Broca's area within the frontal lobe.
  • Speech comprehension is attributed to Wernicke's area, at the temporal-parietal lobe junction.

• Cranial Bones

  • The temporal bones are situated at the base and sides of the skull, lateral to the temporal lobes of the brain.
  • The squamosal suture separates the parietal bone and squama portion of temporal bone.
  • The sphenosquamosal suture separates the sphenoid bone and squama portion of temporal bone.
  • Finally, the squamosal suture separates the parietal and temporal bones.
  • The greater wings form the floor of the middle cranial fossa that houses the frontal lobes and pituitary gland, and also the posterior wall of the orbit.
