Examples of hemisphere in the following topics:
-
- The extent of specialization by hemisphere remains under investigation.
- The structural and chemical variance of a particular brain function, between the two hemispheres of one brain or between the same hemisphere of two different brains, is still being studied.
- Although 95% of right-handed people have left-hemisphere dominance for language, 18.8% of left-handed people have right-hemisphere dominance for language function.
- Feeding is an example of a routine left-hemisphere behavior, while escape from predators is an example of a right-hemisphere behavior.
- The human brain is divided into two hemispheres–left and right.
-
- The motor areas, arranged like a pair of headphones across both cortex hemispheres, are involved in the control of voluntary movements.
- The motor areas of the brain are located in both hemispheres of the cortex.
- It is located on the midline
surface of the hemisphere anterior to the primary motor cortex.
-
- The cerebrum contains the cerebral cortex (of the two cerebral hemispheres), as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb.
- The cortex is composed
of two hemispheres, right and left, separated by a large
sulcus.
- A thick fiber bundle, the corpus callosum, connects the two
hemispheres, allowing information to be passed from one side to the
other.
- The right hemisphere controls and processes signals from the left side
of the body, while the left hemisphere controls and processes signals
from the right side of the body.
- Each
hemisphere of the mammalian cerebral cortex can be broken down into
four functionally and spatially defined lobes: frontal, parietal,
temporal, and occipital.
-
- The cerebral hemispheres form the
largest part of the human brain and are situated above most other brain structures.
- The left and right hemispheres of the cerebral cortex are nearly symmetrical.
- The hemispheres are connected by the corpus callosum, the largest white-matter
structure in 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).
-
- Commissural tracts cross from one cerebral hemisphere to the other through bridges called commissures.
- Association tracts connect different regions within the same hemisphere of the brain.
- Long association fibers connect different lobes of a hemisphere to each other, whereas short association fibers connect different gyri within a single lobe.
- It connects the left and right cerebral hemispheres and facilitates interhemispheric communication.
-
- This is imperative in understanding that the left hemisphere of the brain controls the RIGHT side of the body, while the right hemisphere of the brain controls the LEFT side of the body.
-
- Brain metastasis in the right cerebral hemisphere from lung cancer shown on T1-weighted magnetic resonance imaging with intravenous contrast.
-
- The cerebellum has the appearance of a separate structure attached to the bottom of the brain, tucked underneath the cerebral hemispheres.
- Like the cerebral cortex, the cerebellum is divided into two hemispheres.
-
- Grey matter is distributed at the surface of the cerebral hemispheres and cerebellum, as well as in the depths of the cerebrum, cerebellar, brainstem, and spinal grey matter.
-
- The fat-transfer approach effects the augmentation, and corrects the contour defects of the breast hemisphere with grafts of autologous adipocyte fat tissue.
