Angélique Arvanitaki
Angélique Arvanitaki (; 11 July 1901 – 6 October 1983) was a French neurophysiologist who did research on the electrical activity of neurons using the large nerve fibres of several different molluscs. Life Angélique Arvanitaki was of Greek origin and was born in Cairo on 11 July 1901. In 1942, she married Nick Chalazonitis, who was a student in veterinary medicine at the time, and would himself become a neurophysiologist too. Their daughter Alcmene Chalazonitis, born in 1943, later also became a neuroscientist. Research Arvanitaki contributed to the field of neurophysiology with research that explored the giant nerve fibres in genera of gastropods, the sea hare ''Aplysia'' and the land snail ''Helix''. She developed the concept of ganglion preparation of large identifiable nerves. Arvanitaki also discovered that regular electrical oscillations could periodically grow in size until a series of action potentials were fired along isolated nerve fibres of the cuttlefish, g ...

Ladislav Tauc
Ladislav Tauc (1926–1999) was a French neuroscientist, born in Pardubice, Czechoslovakia. He was a pioneer in neuroethology and neuronal physiology, who immigrated to France in 1949 to work at the Institut Marey in Paris. Tauc was the founder and former director of the Laboratoire de Neurobiologie Cellulaire et Moléculaire of the French National Centre for Scientific Research (CNRS). He was one of the teachers of Eric R. Kandel. There Eric R. Kandel started to investigate the gill withdrawal reflex and postsynaptic potentials (PSP) in identified neurons in the abdominal ganglion of Aplysia. "The introduction of a 'simplified' brain (the ''Aplysia'' nervous system) to study the cellular and molecular basis of organized neuronal interactions, has been described as one of Tauc’s essential contributions to neuroscience." Since the year 2000 an annual meeting is organized in honor of Ladislav Tauc. See also * Eric R. Kandel * Torsten Wiesel * Stephen Kuffler Stephen W ...

Women Physiologists
A woman is an adult female human. Before adulthood, a female child or Adolescence, adolescent is referred to as a girl. Typically, women are of the female sex and inherit a pair of X chromosomes, one from each parent, and women with functional uteruses are capable of pregnancy and giving childbirth, birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, ''SRY'' gene on either one of the respective sex chromosomes. Sex differences in human physiology, Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. An adult woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. These characteristics facilitate childbirth and breastfeeding. Women typically have less facial and other body hair, have a higher body fat composition, and are on average shorter and less ...

Electrophysiologists
Electrophysiology (from [see the Electron#Etymology, etymology of "electron"]; ; and ) is the branch of physiology that studies the electrical properties of biological cell (biology), cells and tissues. It involves measurements of voltage changes or electric current or manipulations on a wide variety of scales from single ion channel proteins to whole organs like the heart. In neuroscience, it includes measurements of the electrical activity of neurons, and, in particular, action potential activity. Recordings of large-scale electric signals from the nervous system, such as electroencephalography, may also be referred to as electrophysiological recordings. They are useful for electrodiagnostic medicine, electrodiagnosis and monitoring (medicine), monitoring. Definition and scope Classical electrophysiological techniques Principle and mechanisms Electrophysiology is the branch of physiology that pertains broadly to the flow of ions (ion current) in biological tissues and, in p ...

Squid
A squid (: squid) is a mollusc with an elongated soft body, large eyes, eight cephalopod limb, arms, and two tentacles in the orders Myopsida, Oegopsida, and Bathyteuthida (though many other molluscs within the broader Neocoleoidea are also called ''squid'' despite not strictly fitting these criteria). Like all other cephalopods, squid have a distinct head, Symmetry (biology)#Bilateral symmetry, bilateral symmetry, and a mantle (mollusc), mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar Ecological niche, role to teleost fish as open-water predators of similar size and behaviour. They play an important role in the open-water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axon
An axon (from Greek ἄξων ''áxōn'', axis) or nerve fiber (or nerve fibre: see American and British English spelling differences#-re, -er, spelling differences) is a long, slender cellular extensions, projection of a nerve cell, or neuron, in Vertebrate, vertebrates, that typically conducts electrical impulses known as action potentials away from the Soma (biology), nerve cell body. The function of the axon is to transmit information to different neurons, muscles, and glands. In certain sensory neurons (pseudounipolar neurons), such as those for touch and warmth, the axons are called afferent nerve fibers and the electrical impulse travels along these from the peripheral nervous system, periphery to the cell body and from the cell body to the spinal cord along another branch of the same axon. Axon dysfunction can be the cause of many inherited and acquired neurological disorders that affect both the Peripheral nervous system, peripheral and Central nervous system, central ne ...
