brain functionmammalian braincerebral
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. The brain is located in the head, usually close to the sensory organs for senses such as vision. The brain is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons.

Ancient Egyptian concept of the soul

The ancient Egyptians believed that a soul (kꜣ/bꜣ; Egypt. pron. ka/ba) was made up of many parts. In addition to these components of the soul, there was the human body (called the ḥꜥ, occasionally a plural ḥꜥw, meaning approximately "sum of bodily parts").

Pink noise

1/f noisepink1/''f'' noise
Pink noise or 1⁄f noise is a signal or process with a frequency spectrum such that the power spectral density (energy or power per frequency interval) is inversely proportional to the frequency of the signal. Pink noise is the most common signal in biological systems. In pink noise, each octave (halving/doubling in frequency) carries an equal amount of noise energy. The name arises from the pink appearance of visible light with this power spectrum. This is in contrast with white noise which has equal intensity per frequency interval.

Han Xiangzi

Han Xiang ZiHon Seung-ziPhilosopher Hon Sheung
Han Xiangzi, courtesy name Qingfu or Beizhu, is a Chinese mythological figure and one of the Eight Immortals in the Taoist pantheon. He studied Taoist magical arts under the tutelage of Lü Dongbin, another of the Eight Immortals. Han Xiangzi is often depicted carrying a dizi (Chinese flute), so he is also regarded as the patron deity of flutists. He is also believed to be the composer of the Taoist musical piece Tian Hua Yin .


A bassinet, bassinette, or cradle is a bed specifically for babies from birth to about four months. Bassinets are generally designed to work with fixed legs or casters, while cradles are generally designed to provide a rocking or gliding motion. Bassinets and cradles are distinguished from Moses baskets and carry cots, which are designed to be carried and sit directly on the floor or furniture. After four months, babies are often transferred to a crib (North American usage) or cot (UK usage). In the United States, however, the bedside sleeper is the prevalent option, since they are generally bigger, recommended up to 6 months, and often used up to a year.


Taoism, or Daoism, is a religious or philosophical tradition of Chinese origin which emphasizes living in harmony with the Tao (, also romanized as Dao). The Tao is a fundamental idea in most Chinese philosophical schools; in Taoism, however, it denotes the principle that is the source, pattern and substance of everything that exists. Taoism differs from Confucianism by not emphasizing rigid rituals and social order, but is similar in the sense that it is a teaching about the various disciplines for achieving "perfection" by becoming one with the unplanned rhythms of the universe called "the way" or "dao".


The gravitational force, or more commonly, g-force, is a measurement of the type of acceleration that causes a perception of weight. Despite the name, it is incorrect to consider g-force a fundamental force, as "g-force" is a type of acceleration that can be measured with an accelerometer. Since g-force accelerations indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). When the g-force acceleration is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of an object's mass.

High-G training

centrifugecentrifugeshuman centrifuge
High-G training is done by aviators and astronauts who are subject to high levels of acceleration ('G'). It is designed to prevent a g-induced loss of consciousness (G-LOC), a situation when the action of g-forces move the blood away from the brain to the extent that consciousness is lost. Incidents of acceleration-induced loss of consciousness have caused fatal accidents in aircraft capable of sustaining high-g for considerable periods.


Hindus are persons who regard themselves as culturally, ethnically, or religiously adhering to aspects of Hinduism. Historically, the term has also been used as a geographical, cultural, and later religious identifier for people indigenous to the Indian subcontinent.

Head-mounted display

A head-mounted display (or helmet-mounted display, for aviation applications), both abbreviated HMD, is a display device, worn on the head or as part of a helmet, that has a small display optic in front of one (monocular HMD) or each eye (binocular HMD). A HMD has many uses, including in gaming, aviation, engineering, and medicine lift. A head-mounted display is the primary component of virtual reality headsets.

Yoga Vasistha

Laghu-yoga-vasisthaPadārtha abhāvanaVasishta Ramayana
Yoga Vasistha (योग-वासिष्ठ, IAST: ) is a philosophical text attributed to Valmiki, although the real author is unknown. The complete text contains over 29,000 verses. The short version of the text is called Laghu Yogavasistha and contains 6,000 verses. The exact century of its completion is unknown, but has been estimated to be somewhere between 6th-century to as late as 14th-century, but it is likely that a version of the text existed in the 1st millennium.


Proprioception, is the sense of the relative position of one's own parts of the body and strength of effort being employed in movement. It is sometimes described as the "sixth sense".


VālmīkiBalmikiMaharishi Valmiki
Valmiki (Sanskrit: वाल्मीकि, Vālmīki) is celebrated as the harbinger-poet in Sanskrit literature. The epic Ramayana, dated variously from 5th century BCE to first century BCE, is attributed to him, based on the attribution in the text itself. He is revered as Ādi Kavi, the first poet, author of Ramayana, the first epic poem.

Cognitive science

cognitive scientistcognitive sciencescognitive
Cognitive science is the interdisciplinary, scientific study of the mind and its processes. It examines the nature, the tasks, and the functions of cognition (in a broad sense). Cognitive scientists study intelligence and behavior, with a focus on how nervous systems represent, process, and transform information. Mental faculties of concern to cognitive scientists include language, perception, memory, attention, reasoning, and emotion; to understand these faculties, cognitive scientists borrow from fields such as linguistics, psychology, artificial intelligence, philosophy, neuroscience, and anthropology.


However, Indian doctrines influenced Western thinking via the Theosophical Society, a New Age group which became popular among Euro-American intellectuals. Psychology was a popular topic in Enlightenment Europe. In Germany, Gottfried Wilhelm Leibniz (1646–1716) applied his principles of calculus to the mind, arguing that mental activity took place on an indivisible continuum—most notably, that among an infinity of human perceptions and desires, the difference between conscious and unconscious awareness is only a matter of degree. Christian Wolff identified psychology as its own science, writing Psychologia empirica in 1732 and Psychologia rationalis in 1734.

Paramahansa Yogananda

YoganandaYogananda, ParamahansaSwami Yogananda
Yogananda gave a general description of Kriya Yoga in his Autobiography: The Kriya Yogi mentally directs his life energy to revolve, upward and downward, around the six spinal centers (medullary, cervical, dorsal, lumbar, sacral, and coccygeal plexuses) which correspond to the twelve astral signs of the zodiac, the symbolic Cosmic Man. One-half minute of revolution of energy around the sensitive spinal cord of man effects subtle progress in his evolution; that half-minute of Kriya equals one year of natural spiritual unfoldment.

Memory is the faculty of the brain by which information is encoded, stored, and retrieved when needed.


imaginativeimaginaryimaginative faculty
Imagination is the ability to produce images, ideas and sensations in the mind without any immediate input of the senses (such as seeing or hearing). It is also described as the forming of experiences in the mind, which can be recreations of past experiences such as vivid memories with imagined changes or that they are completely invented. Imagination helps make knowledge applicable in solving problems and is fundamental to integrating experience and the learning process. A basic training for imagination is listening to storytelling (narrative), in which the exactness of the chosen words is the fundamental factor to "evoke worlds".


The Mahābhārata is one of the two major Sanskrit epics of ancient India, the other being the Rāmāyaṇa. It narrates the struggle between two groups of cousins in the Kurukshetra War and the fates of the Kaurava and the Pāṇḍava princes and their succession. Along with the Rāmāyaṇa, it forms the Hindu Itihasa.
