Raichle coined the term "default mode" in 2001 to describe resting state brain function; [19] the concept rapidly became a central theme in neuroscience. [20] Around this time the idea was developed that this network of brain areas is involved in internally directed thoughts and is suspended during specific goal-directed behaviors.
Imagination – the ability to form new images and sensations that are not perceived through sight, hearing, or other senses; Wakefulness. Pre-attentive processing – the unconscious accumulation of information from the environment; Preconscious – information that is available for cognitive processing but that currently lies outside ...
Body image is a complex construct, [1] often used in the clinical context of describing a patient's cognitive perception of their own body. The medical concept began with the work of the Austrian neuropsychiatrist and psychoanalyst Paul Schilder , described in his book The Image and Appearance of the Human Body first published in 1935.

Although the human brain represents only 2% of the body weight, it receives 15% of the cardiac output, 20% of total body oxygen consumption, and 25% of total body glucose utilization. [138] The brain mostly uses glucose for energy, and deprivation of glucose, as can happen in hypoglycemia , can result in loss of consciousness. [ 139 ]
Venus with a Mirror (1555) by Titian. Body image is a person's thoughts, feelings and perception of the aesthetics or sexual attractiveness of their own body. [1] [2] The concept of body image is used in several disciplines, including neuroscience, psychology, medicine, psychiatry, psychoanalysis, philosophy, cultural and feminist studies; the media also often uses the term.
The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.
Sagittal view of cingulate region of human brain with a Talairach grid superimposed in accordance with standard locators. Talairach coordinates, also known as Talairach space, is a 3-dimensional coordinate system (known as an 'atlas') of the human brain, which is used to map the location of brain structures independent from individual differences in the size and overall shape of the brain.
The brain is made up of individual cells (neurons) that contain specialized features such as dendrites, a cell body, and an axon. Neurons are cells differentiable from other tissues in the body. Neurons differ in size, shape, and structure according to their location or functional specialization.
