Overview of neuron structure and function - Khan Academy
Individual neurons connect to other neurons to stimulate or inhibit their activity, forming circuits that can process incoming information and carry out a response. Neuronal circuits can be very …
The neural correlates of consciousness (video) | Khan Academy
Neuroscientists are making great strides in identifying the neural processes that make a difference to particular phenomenally conscious experiences. But this is just one piece of the puzzle.
Sensory processing and the brain (article) | Khan Academy
Information from sensory receptors is transmitted, or passed along, nerve cells to the brain. The brain processes, or organizes, information from different sensory receptors. The brain can …
Overview of neuron structure (types of neurons) - Khan Academy
In the central nervous system, neurons start as neural stem cells, which turn into most of the cell types of the central nervous system. And these neural stem cells then differentiate into cells …
Signal propagation: The movement of signals between neurons
And it’s in our best interests that this action-reaction process goes quickly – so that we can catch ourselves as we fall, or shut our eyes tight. The process of sending these signals takes place …
Renal physiology: Glomerular filtration - Khan Academy
Neural (nervous system) control and hormonal control - these extrinsic mechanisms can override renal autoregulation and decrease the glomerular filtration rate when necessary.
How neural networks work (video) | Khan Academy
In this video, you'll learn how AI scientists built artificial neural networks that can gather information from various sources and synthesize them into an insight, and how additional …
Human embryogenesis (article) | Khan Academy
The notochord causes the ectoderm above it to form a thick flat plate of cells called the neural plate. The neural plate extends the length of the rostral-caudal axis. The neural plate then …
Neuron action potentials: The creation of a brain signal
Action potentials (those electrical impulses that send signals around your body) are nothing more than a temporary shift (from negative to positive) in the neuron’s membrane potential caused …
The synapse (article) | Human biology | Khan Academy
Functionally related neurons connect to form neural networks (also known as neural nets or assemblies). The connections between neurons are not static, though, they change over time. …
