What is the definition of brain plasticity?
Brain plasticity is also known as neuroplasticity. It is the ability of the brain to modify itself by forming neural connections.
Out of the four types of neural circuits diverging converging reverberating and parallel after-discharge which is likely to fire the longest after a stimulus ceases?
Reverberating.
What is an artificial neural network and how does it work?
Artificial neural networks are computational models inspired by an animal's central nervous systems (in particular the brain) which is capable of machine learning as well as pattern recognition. They work by neurons continuously evaluating their output by looking at their inputs, calculating the weighted sum and comparing to a threshold to decide if they should fire.
Which of the following are specialized cells blood cells muscle cells bone cells all of the above?
All.
Do people have prokaryotic or eukaryotic cells?
The cells found in the human body are eukaryotic cells. Organisms that have eukaryotic cells are usually multicellular like humans. Organisms that have prokaryotic cells are usually unicelluar, like bacteria.
Muscle cells gland cells and specialized cells that respond to neural stimuli are called?
effectors
Where do Preganglionic neurons develop from?
Neural crest cells
The receptor cells that convert light energy into neural signals are called?
Bipolar cells
What is a neurohormone?
A neurohormone is a hormone that is secreted and circulated by neurosecretory cells into the blood. It stimulates neural mechanisms when activated by neural stimuli.
In a toad embryo the neural tube does what?
The neural tube is the embryonic predecessor of the brain and spinal cord. Which means, most of what it "does" is develop into a brain and spinal cord. The neural tube is initially formed almost exclusively of stem and progenitor cells. Over time, these stem and progenitor cells adopt specific identities and begin to differentiate neurons and later glial cells and these cells begin forming neural circuits. By the time the neural tube has developed to a point where it is capable of carrying out rudimentary neurological functions, the nomenclature is generally changed to brain and spinal cord rather than neural tube.
What happens to neural crest cells?
the produce sexual cells, while the metosis dies because of doing it
What type of neural tissue compose the corpus callosum?
glial cells
What are neural mechanisms?
Neural Mechanisms refer to structures such as neurons (nerve cells), neural circuits and regions of the brain plus substances such as neurotransmitters and hormones. These regulate behaviour, voluntary and involuntary systems.
Cells are organized into blank such as muscle neural and cardiac?
Cells that are the same form tissues. Muscle cells form muscle tissue.
What is neural convergence?
Neural convergence refers to the phenomenon of multiple sensory receptors giving information to a smaller number of neural cells. For example, in the retinal periphery, many photoreceptors converge on a smaller number of ganglion cells so that the brain doesn't have to process inputs from each photoreceptor.
What are the type of Cells of neural tissue that support the tissue called?
Nervous tissue is composed of neurons and supporting cells called neuroglial. The neuroglial are unspecialized cells and are able to perform supporting functions unlike the neurons which are used in key functions.
Computer circuits that stimulate the brain's interconnected nerve cells?
neural networks
