Neurons are highly specialized for the processing and transmission of cellular signals. Given the diversity of functions performed in different parts of the nervous system, there is a wide variety in their shape, size, and electrochemical properties. For instance, the soma of a neuron can vary from 4 to 100 micrometers in diameter. [7]
The bird brain is divided into a number of sections, each with a different function. The cerebrum or telencephalon is divided into two hemispheres , and controls higher functions. The telencephalon is dominated by a large pallium , which corresponds to the mammalian cerebral cortex and is responsible for the cognitive functions of birds.
A part of the discoveries that resulted in them winning the 1981 Nobel Prize [15] was that there were cortical columns in vision as well, and that the neighboring columns were also related in function in terms of the orientation of lines that evoked the maximal discharge. Hubel and Wiesel followed up on their own studies with work demonstrating ...
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges, blood vessels, and ducts. The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells, also known as neuroglia. [1]
Information about the structure and function of the human brain comes from a variety of experimental methods, including animals and humans. Information about brain trauma and stroke has provided information about the function of parts of the brain and the effects of brain damage. Neuroimaging is used to visualise the brain and record brain ...
Most famous parts of the brain highlighted in different colours. The human brain anatomical regions are ordered following standard neuroanatomy hierarchies. Functional, connective, and developmental regions are listed in parentheses where appropriate.
The latest research looked at a part of the brain called the olfactory bulb, which processes information about smell. Humans have two olfactory bulbs, one above each nasal cavity. Humans have two ...
Based upon its structure and connectivity, its function is suggested to be related to coordination of different brain functions; i.e. the conductor analogy. Consciousness functionally can be divided into two components: (i) wakefulness, which is arousal and alertness; (ii) content of consciousness, which is the processing of content.
