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 simple, and …
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.
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 inputs can be used to train …
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 then trigger a …
The hard problem of consciousness (video) | Khan Academy
It is important to be clear here that no one denies that neural states are relevant for consciousness. The issue is whether we can say that consciousness is nothing above and beyond what goes on in the …
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 in two …
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 called …
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. The …
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.
Introduction to neural cell types (video) | Khan Academy
Explore the world of neural cells, the building blocks of our nervous system. Uncover the roles and functions of neurons and glia, and how they work together to regulate our body's functions.
