10–20 system (EEG)

Index 10–20 system (EEG)

The 10–20 system or International 10–20 system is an internationally recognized method to describe and apply the location of scalp electrodes in the context of an EEG exam, Polysomnograph sleep study, or voluntary lab research/experiment. [1]

Corpus callosum

The corpus callosum (Latin for "tough body"), also callosal commissure, is a wide commissure, a flat bundle of commissural fibers, about 10 cm long beneath the cerebral cortex in the brains of placental mammals.

Lateralization of brain function

The lateralization of brain function is the tendency for some neural functions or cognitive processes to be specialized to one side of the brain or the other.

Lobe (anatomy)

In anatomy, a lobe is a clear anatomical division or extension of an organ (as seen for example in the brain, the lung, liver or the kidney) that can be determined without the use of a microscope at the gross anatomy level.

Parietal lobe

The parietal lobe is one of the four major lobes of the cerebral cortex in the brain of mammals. The parietal lobe is positioned above the temporal lobe and behind the frontal lobe and central sulcus. The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch (mechanoreception) in the somatosensory cortex which is just posterior to the central sulcus in the postcentral gyrus, and the dorsal stream of the visual system. The major sensory inputs from the skin (touch, temperature, and pain receptors), relay through the thalamus to the parietal lobe. Several areas of the parietal lobe are important in language processing. The somatosensory cortex can be illustrated as a distorted figure – the homunculus (Latin: "little man"), in which the body parts are rendered according to how much of the somatosensory cortex is devoted to them.Schacter, D. L., Gilbert, D. L. & Wegner, D. M. (2009). Psychology. (2nd ed.). New York (NY): Worth Publishers. The superior parietal lobule and inferior parietal lobule are the primary areas of body or spacial awareness. A lesion commonly in the right superior or inferior parietal lobule leads to hemineglect. The name comes from the parietal bone, which is named from the Latin paries-, meaning "wall".

Scientific method

Scientific method is an empirical method of knowledge acquisition, which has characterized the development of natural science since at least the 17th century, involving careful observation, which includes rigorous skepticism about what one observes, given that cognitive assumptions about how the world works influence how one interprets a percept; formulating hypotheses, via induction, based on such observations; experimental testing and measurement of deductions drawn from the hypotheses; and refinement (or elimination) of the hypotheses based on the experimental findings.
