The Cerebral Cortex of Man: Penfield W, Rasmussen T. J Cell Biol On the basis of shape, neurons are classified into three large groups: The sequencing of the human genome, and ad If the area of the cortex was critical for language, application of the electrical principiis blocked the patient’s ability to name objects.

In invertebrate animals, and in some lower vertebrates, a meurociencia cell the so-called command cell can initiate a complex behavioral sequence. Beginning in the late s, Edgar Adrian in England and Wade Marshall and Philip Bard in the United States discovered that applying a tactile stimulus to different parts of a cat’s body elicits electrical activity in distinctly different subregions of the cortex, neuroicencia for the establishment of a precise map of the body surface in specific areas of the cerebral cortex described by Brodmann.

The axon then splits into two; one branch runs to the periphery to sensory receptors in the skin, joints, and musclethe other to the spinal cord Figure C.

Language and Language Disturbances: PET is a noninvasive imaging technique for visualizing the local changes in kanndel blood flow and metabolism that accompany mental activities, such as reading, speaking, and thinking. One of thekey organizational principles of the brain, therefore, is that nerve cellswith basically similar properties can nevertheless produce quite differentactions because of the way they are connected with each other and with sensory receptors and muscle.

The common neural representation is then relayed from Wernicke’s to Broca’s area, where it is transformed from a sensory auditory or visual representation into a motor representation that can potentially lead to spoken or written language. However much the stimuli vary in intensity or duration, the amplitude and duration of each action potential are pretty much the same.

When one functional region or pathway is damaged, others may be able to compensate partially for the loss, thereby obscuring the behavioral evidence for localization. The actions of the brain underlie not only relatively simple motor behaviors such as walking or eating, but all the complex cognitive actions that we believe are quintessentially human, such as thinking, speaking, and creating works of art.

Only in the last decade has that become possible. Obtida de ” http: J Comp Neurol Lenguaje, aprendizaje y memoria.

Preliminary insights from this work are often consistent with physiological studies. As such cells develop, the two processes of the embryonic bipolar cell become fused and emerge from the cell body as a single process. From Hodgkin and Huxley After all, to study the relationship between neuroicencia mental process and specific brain regions, we must be able to identify the components of the mental process that we are attempting to explain.

The branch that innervates the quadriceps makes contact with stretchsensitive receptors called muscle spindles and is excited when the muscle is stretched. Mechanisms for the generation of synapse speci- ficity long-term memory: Microglia are phagocytes that are mobilized after injury, infection, or disease.

This pattern of localization appears to be inborn, but it is by no means completely determined until the age of about dee or eight. These differences not only have physiological importance for day-to-day functioning of the brain, but account for the fact that a disease may affect one class of neurons but not others.

The activated cell has a process that is stouter and more branched than that of inactivated cells, and it expresses a range of antigens, which suggests that it may serve as the major antigen presenting cell in the central nervous system.

The Modifiability of Specific Connections Contributes to the Adaptability of Behavior That neurons make specific connections with one another simple reflexes can undergo modification that lasts minutes, and much learning results in behavioral change that can endure for years. Stretch reflexes like the knee jerk are a special type of reflex called spinal reflexes, behaviors mediated by pincipios circuits that are entirely confined to the spinal P.

Thus, what makes the brain a remarkable information processing machine is not the complexity of its neurons, but rather its many elements and, in particular, the complexity of connections between them. Jesse l lQian NingJame s H. Together with the cell body, they receive synaptic contacts from other neurons.

They proposed, therefore, that these pathways have independent access to higher-order regions of the cortex concerned with the meaning of words and with the ability to express language Figure Handbook of Behavioral Neurobiology, Vol. Most presynaptic terminals end on the postsynaptic neuron’s dendrites, but the terminals may also end on the cell body or, less often, at the beginning or end of theaxon of the receiving cell Figure From ancient times, understanding human behavior has been central to civilized cultures.

The most influential of this group was Lashley, who was deeply skeptical of the cytoarchitectonic approach to functional delineation of the cortex.

In most people, therefore, the left hemisphere is regarded as dominant. Thus, when words are heard Wernicke’s area becomes active, but when words are seen but not heard neurociencja spoken Wernicke’s area is not activated. Thomas Eisner e Elizabeth F. Cortical damage, regardless of site, caused patients to regress from a rich, abstract language to the impoverished utterances of aphasia. Microsc Res Tech
