Synapse
In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another cell (neural or otherwise). Santiago Ramón y Cajal proposed th...

New 'Artificial Synapses' Could Let Supercomputers Mimic the Human Brain
Brain-like machines with human-like abilities to solve problems could become a reality, researchers say.
Your Brain Has A "Delete" Button--Here's How To Use It
This is the fascinating way that your brain makes space to build new and stronger connections so you can learn more.
Only The Lonely - A Surprise Role For Dopamine In Social Interplay
Scientists have shown that the chemical signal dopamine plays an unexpected role in social interactions. In mice, nerve cells in the brain that release dopamine become particularly active in animals k...
How Synapses Work
Salk scientists computationally reconstructed brain tissue in the hippocampus to study the sizes of connections (synapses). The larger the synapse, the more likely the neuron will send a signal to a n...
Boston University's 3D map reveals tiny connections between cells
Harvard University researchers hope the map could be used to identify unusual connections between brain cells that could shed light on disorders such as bipolar and depression.
Scientists Discover Atomic-Resolution Details Of Brain Signaling
Scientists have revealed never-before-seen details of how our brain sends rapid-fire messages between its cells. They mapped the 3-D atomic structure of a two-part protein complex that controls the re...
Swedish Scientists Build Artificial Neurons Able To Communicate With Organic Neurons
Scientists at Karolinska Institutet in Sweden have built a fully functional neuron by using organic bioelectronics. This artificial neuron contain no "living" parts, but is capable of mimicking the fu...
Brain Receptor Found To Significantly Affect Cocaine Addiction
The study found that by manipulating the activity of Activin receptors — receptors found in the brain — the researchers were able to increase or decrease cocaine-taking and relapse behavior in animal ...
Nootropics? Enhancing Brain Power?
Nootropics are smart drugs, memory enhances and cognitive enhancers. Is intelligence enhanced or your neuro system made better by using nootropics? There are supplements, nutraceuticals, functional fo...

Axon
An axon (from Greek ἄξων áxōn, axis), also known as a nerve fibre, is a long, slender projection of a nerve cell, or neuron, that typically conducts electrical impulses away from the neuron's cell bod...

Chemical synapse
Chemical synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. Chemical synapses allow neurons to form circuits wi...
Action potential
In physiology, an action potential is a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls, following a consistent trajectory. Action potentials occur in...

Excitatory synapse
An excitatory synapse is a synapse in which an action potential in a presynaptic neuron increases the probability of an action potential occurring in a postsynaptic cell. Neurons form networks throug...

Neurotransmission
Neurotransmission (Latin: transmissio = passage, crossing; from transmitto = send, let through), also called synaptic transmission, is the process by which signaling molecules called neurotransmitters...
Synaptic vesicle
In a neuron, synaptic vesicles (or neurotransmitter vesicles) store various neurotransmitters that are released at the synapse. The release is regulated by a voltage-dependent calcium channel. Vesicl...

Active zone
The active zone or synaptic active zone is a term first used by Couteaux and Pecot-Dechavassinein in 1970 to define the site of neurotransmitter release. Two neurons make contact through structures ca...

Postsynaptic potential
Postsynaptic potentials are changes in the membrane potential of the postsynaptic terminal of a chemical synapse. Postsynaptic potentials are graded potentials, and should not be confused with acti...

Electrical synapse
An electrical synapse is a mechanical and electrically conductive link between two abutting neurons that is formed at a narrow gap between the pre- and postsynaptic neurons known as a gap junction. A...
Ribbon synapse
The ribbon synapse is a type of neuronal synapse characterized by unique mechanisms of multivesicular release and calcium channel positioning that promote rapid neurotransmitter release and signal tra...
Neuromuscular junction
The neuromuscular junction connects the nervous system to the muscular system via synapses between efferent nerve fibers and muscle fibers, also known as muscle cells. As an action potential reaches t...

Immunological synapse
In immunology, an immunological synapse (or immune synapse) is the interface between an antigen-presenting cell or target cell and a lymphocyte such as an effector T cell or Natural Killer cell. It is...
Synaptic plasticity
In neuroscience, synaptic plasticity is the ability of synapses to strengthen or weaken over time, in response to increases or decreases in their activity. Plastic change also results from the alterat...
Long-term potentiation
In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of activity. These are patterns of synaptic activity that produce a long-lasting increa...

Synaptic fatigue
Synaptic fatigue, or short-term synaptic depression, is an activity-dependent form of short term synaptic plasticity that results in the temporary inability of neurons to fire and therefore transmit a...
