Meynert
Theodor Hermann Meynert (15 June 1833 – 31 May 1892) was a German-Austrian psychiatrist, neuropathologist and anatomist born in Dresden. Meynert believed that disturbances in brain development could be a predisposition for psychiatric illness and that certain psychoses are reversible. In 1861 he earned his medical doctorate, and in 1875 became director of the psychiatric clinic associated with the University of Vienna. Some of his better known students in Vienna were Josef Breuer, Sigmund Freud, who in 1883 worked at Meynert's psychiatric clinic, and Julius Wagner-Jauregg, who introduced fever treatment for syphilis. Meynert later distanced himself from Freud because of the latter's involvement with practices such as hypnosis. Meynert also ridiculed Freud's idea of male hysteria; though some authors believe this to be due to his own hidden suffering of the illness, prompting a reconciliation with Freud near to his death. Other famous students of Meynert's were Russian neuropsychi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal Optic Nucleus Of Meynert
The nucleus basalis, also known as the nucleus basalis of Meynert or nucleus basalis magnocellularis, is a group of neurons located mainly in the substantia innominata of the basal forebrain. Most neurons of the nucleus basalis are rich in the neurotransmitter acetylcholine, and they have widespread projections to the neocortex and other brain structures. Structure The nucleus basalis in humans is a somewhat diffuse collection of large cholinergic neurons in the basal forebrain. The main body of the nucleus basalis lies inferior to the anterior commissure and the globus pallidus, and lateral to the anterior hypothalamus in an area known as the substantia innominata. Rostrally, the nucleus basalis is continuous with the cholinergic neurons of the nucleus of the diagonal band of Broca. The nucleus basalis is thought to consist of several subdivisions based on the location of the cells and their projections to other brain regions. Occasional neurons belonging to the nucleus bas ...

Carl Wernicke
Carl (or Karl) Wernicke (; ; 15 May 1848 – 15 June 1905) was a German physician, anatomist, psychiatrist and neuropathologist. He is known for his influential research into the pathological effects of specific forms of encephalopathy and also the study of receptive aphasia, both of which are commonly associated with Wernicke's name and referred to as Wernicke encephalopathy and Wernicke's aphasia, respectively. His research, along with that of Paul Broca, led to groundbreaking realizations of the localization of brain function, specifically in speech. As such, Wernicke's area (a.k.a. Wernicke's Speech Area) has been named after the scientist. Biography Wernicke was born on May 15, 1848, in Tarnowitz, a small town in Upper Silesia, Prussia, now Tarnowskie Góry, Poland. He obtained his secondary education at the gymnasium in Oppeln, which is a school near the university of Breslau. Wernicke then studied medicine at the University of Breslau and did graduate work studying langu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Substantia Innominata Of Meynert
The substantia innominata also innominate substance, or substantia innominata of Meynert (Latin for unnamed substance) is a series of layers in the human brain consisting partly of grey matter, gray and partly of white matter, which lies below the anterior part of the thalamus and lentiform nucleus. It is included as part of the anterior perforated substance (as it appears to be perforated by many holes which are actually blood vessels). It is part of the basal forebrain structures and includes the nucleus basalis. A portion of the substantia innominata, below the globus pallidus is considered as part of the extended amygdala. Layers It consists of three layers, superior, middle, and inferior. * The ''superior layer'' is named the ansa lenticularis, and its fibers, derived from the medullary lamina of the lentiform nucleus, pass medially to end in the thalamus and subthalamic region, while others are said to end in the tegmentum and red nucleus. * The ''middle layer'' consists of ...

Cytoarchitectonics Of The Cerebral Cortex
Cytoarchitecture (Greek '' κύτος''= "cell" + '' ἀρχιτεκτονική''= "architecture"), also known as cytoarchitectonics, is the study of the cellular composition of the central nervous system's tissues under the microscope. Cytoarchitectonics is one of the ways to parse the brain, by obtaining sections of the brain using a microtome and staining them with chemical agents which reveal where different neurons are located. The study of the parcellation of ''nerve fibers'' (primarily axons) into layers forms the subject of myeloarchitectonics ( History of the cerebral cytoarchitecture Defining cerebral cytoarchitecture began with the advent of —the science of slicing a ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auguste-Henri Forel
Auguste-Henri Forel (1 September 1848 – 27 July 1931) was a Swiss myrmecologist, neuroanatomist, psychiatrist and eugenicist, notable for his investigations into the structure of the human brain and that of ants. For example, he is considered a co-founder of the neuron theory. Forel is also known for his early contributions to sexology and psychology. From 1978 until 2000 Forel's image appeared on the 1000 Swiss franc banknote. Biography Born in villa ''La Gracieuse'', Morges, Switzerland, to Victor Forel a pious Swiss Calvinist and Pauline Morin, a French Huguenot he was brought up under a protective household. At the age of seven he began to take an interest in insects. He went to school at Morges and Lausanne before joining the medical school at Zurich. Forel had a diverse and mixed career as a thinker on many subjects. At Zurich he was inspired by the work of Bernhard von Gudden (1824-1886). In 1871 he went to Vienna and studied under Theodor Meynert (1833-1892) but was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forebrain
In the anatomy of the brain of vertebrates, the forebrain or prosencephalon is the Anatomical terms of location#Directional terms, rostral (forward-most) portion of the brain. The forebrain (prosencephalon), the midbrain (mesencephalon), and hindbrain (rhombencephalon) are the three Brain vesicle, primary brain vesicles during the early development of the nervous system. The forebrain controls body temperature, reproductive functions, eating, sleeping, and the display of emotions. At the five-vesicle stage, the forebrain separates into the diencephalon (thalamus, hypothalamus, subthalamus, and epithalamus) and the telencephalon which develops into the cerebrum. The cerebrum consists of the cerebral cortex, underlying white matter, and the basal ganglia. In humans, by 5 weeks in utero it is visible as a single portion toward the front of the fetus. At 8 weeks in utero, the forebrain splits into the left and right cerebral hemispheres. When the embryonic forebrain fails to divide ...
