In a study investigating high-level gait and balance disorders in elderly adults who had no evidence of rheumatologic, orthopedic, or neurologic disease, brain imaging data revealed an association between reduced gray matter density of the PPN and cuneiform nucleus and impaired gait initiation, step execution, and postural control.

Message Signaled Interrupts (MSI) are a method of signaling interrupts, using special in-band messages to replace traditional out-of-band signals on dedicated interrupt lines. While message signaled interrupts are more complex to implement in a device, they have some significant advantages over pin-based out-of-band interrupt signalling, such ...
Cortical stimulation identifies which regions of the brain are vital for certain functions, thereby allowing a 'map' to be made which can be used to decide if brain areas are safe to remove. Cortical stimulation mapping led to the development of a homunculus for the motor and sensory cortices, which is a diagram showing the brain's connections ...
Functional integration is the study of how brain regions work together to process information and effect responses. Though functional integration frequently relies on anatomic knowledge of the connections between brain areas, the emphasis is on how large clusters of neurons – numbering in the thousands or millions – fire together under various stimuli.
The sensorimotor network (SMN), also known as somatomotor network, is a large-scale brain network that primarily includes somatosensory (postcentral gyrus) and motor (precentral gyrus) regions and extends to the supplementary motor areas (SMA). [1] The auditory cortex may also be included, [2] as well as the visual cortex. [3]
Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...

The main dopaminergic pathways of the human brain. Dopaminergic pathways (dopamine pathways, dopaminergic projections) in the human brain are involved in both physiological and behavioral processes including movement, cognition, executive functions, reward, motivation, and neuroendocrine control.
