Movement Control (Muscular Physiology)
Published in Emeric Arus, Biomechanics of Human Motion, 2017
The brain has numerous parts with different functions, but it has four major regions:The cerebrum is composed of the right and left cerebral hemispheres with different functions. The frontal lobe is the center for the intellect and motor control. The temporal lobe is the auditory center. The parietal lobe is the sensory information center. The occipital lobe is the visual input and its interpretation center.The diencephalon is comprised of the thalamus and hypothalamus and is located in the middle of the brain. The thalamus is a sensory integration center. The hypothalamus has many functions but the most important is regulating the homeostasis of the body.The cerebellum has the role of coordinating movement.The brain stem is comprised of the midbrain, the pons, and medulla oblongata. Among many functions, the brain stem is the connection site between the brain and the spinal cord. The spinal cord is connected to the medulla oblongata and has the function of carrying sensory and motor fibers between the brain and the end organs.

The cerebrum consists of dense, convoluted masses of tissue divided into two halves, the left and right cerebral hemispheres, connected by nerve fibers. The cerebrum contains the frontal, parietal, occipital, and temporal lobes. The frontal lobes control skilled motor behavior, including speech, mood, thought, and planning. The parietal lobes interpret sensory information from the rest of the body and control body movement. The occipital lobes deal with vision. The temporal lobes generate memory and motions, process and retrieve long-term memories, and initiate communication or action. The outer layer of each cerebral hemisphere consists of the cortex, the gray matter opposed to the whitish appearance of other brain matter. The cortex is associated with voluntary movement, thought, perception, memory, language, and individuality. Cerebellum

Each part of the brain has been specialized to provide certain functionality. The front section of the cerebrum manages speech, thought, emotion, problem solving, and skilled movements. This part is referred to as the frontal lobe. Moving toward the rear of the head, behind the frontal lobe is the parietal lobe, which identifies and interprets sensations such as touch, temperature, and pain. At the very back of the brain is the occipital lobe, which collects and interprets visual images. On either side of the occipital lobe are the temporal lobes, which process hearing and store memory. The cerebellum coordinates muscle action and is involved with posture and balance maintenance. The cerebellum helps to control and coordinate familiar movements. Initially, when an individual is in the process of learning a new activity, such as riding a bike, the cerebrum directs the muscles to move. At the point where the motion becomes common nature, the cerebellum takes over the muscle controls.

The signals were recorded through all 24 EEG channels of the EasyCap. The analyses were primarily based on the frontal, temporal and occipital region channels (Fp1, Fp2, F3, F4, F7, F8, T7, T8, O1, O2). The channels on the cap and the related brain regions are shown in mutually identical colors in Figure 5. The central electrodes in orange are in the region between the frontal and parietal. The functions of the frontal lobe involve decision-making, controlling emotions and problem-solving. The temporal lobe is important for hearing, long-term memory and speech. The occipital lobe mainly serves on visual perception. Since the diffusion task involves decision-making and memory processes and visual stimuli, the channels in these brain regions were taken into account.
Examining wayfinding behaviours in architectural spaces using brain imaging with electroencephalography (EEG)
Published in Architectural Science Review, 2018
Occipital lobe activity through Alpha waves is more pronounced during wayfinding. The occipital lobe processes all visual information tasks sent by the eye and also plays a role in object recognition (Kacha, Matsumoto, and Mansouri 2015). Alpha waves are believed to increase during wayfinding when objects appear in navigation. In these tests, persons with high visual matching success showed more activity in the occipital lobes.

The frontal lobes play a role in many processes, such as motivation, intention, attention, and concentration. The temporal lobes include regions concerned with memory, visual, and auditory processing. The parietal lobes are associated with perceptual and cognitive integration, memory, and selective attention. The occipital lobes are associated with visual processing.
