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.
Neural tissue is formed by the?
Neural tissue is formed by neural stem cells, which are progenitor cells found in the nervous system. These stem cells have the ability to differentiate into various types of neural cells like neurons, astrocytes, and oligodendrocytes, ultimately forming the intricate network of the nervous system.
Muscle cells gland cells and specialized cells that respond to neural stimuli are called?
Muscle cells are called myocytes, gland cells are called secretory cells, and specialized cells that respond to neural stimuli are called neurons.
Where do neurons originate in the human body?
Neurons originate from neural stem cells in the developing embryo, primarily in the neural tube.
What are the derivatives of neural crest?
Neural crest cells give rise to a variety of cell types, including neurons, glial cells, melanocytes, and certain types of connective tissue. They migrate from the dorsal neural tube during embryonic development to populate different regions of the body. Ultimately, the derivatives of neural crest cells contribute to the formation of structures like the peripheral nervous system, facial bones, and pigment cells in the skin.
What is neural tube and neural crest?
The neural tube is a structure that forms during early embryonic development and eventually develops into the central nervous system, which includes the brain and spinal cord. The neural crest, on the other hand, is a group of cells that arise from the edges of the neural tube and migrate to various parts of the body, giving rise to diverse structures such as peripheral nerves, skin pigment cells, and certain facial features. Both the neural tube and neural crest are crucial for proper neural development and the formation of the nervous system.
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.
The receptor cells that convert light energy into neural signals are called?
The receptor cells that convert light energy into neural signals are called photoreceptor cells. These cells are located in the retina of the eye and are responsible for producing electrical signals in response to light stimulation.
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.
What type of neural tissue compose the corpus callosum?
glial cells
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 is formed from neural crest cells?
Neural crest cells give rise to various cell types including neurons, glial cells, melanocytes, and cells of the peripheral nervous system. They also contribute to structures such as bones, cartilage, and connective tissue in several regions of the body.
