Synapse

POLYCHRONIZAT ION There has been recent experimental evidence that neurons can transmit information through precisely timed spike patterns. Patterns can be found in the precise spike timings of a group of neurons, which form a functional neuron group. Polychronization [20] can be defined as the ability to produce ‘time-locked’ but not synchronous firing patterns with milli-second precision. A network consisting of a group of neurons recurrently connected, with axonal delays and a synaptic…

1. Neurons are the building blocks of the nervous system. Neurons communicate through synapses. The nervous system transmits all messages to the brain. The messaging process moves in one direction to the cell body, where the cell body transmits an electrical pulse to the neurotransmitter this creates an impulse. 2. Throughout the normal day you use multiple parts of your brain. An activity that uses more than ten parts of your brain at once is if you hold your hand over a flame. Your Frontal…

Regulatory Behavior Paper The nervous system is in charge of receiving and relaying the information that is collected; it is also in charge of monitoring and responding to both the internal and the external changes that help to control and coordinate the body’s functions. The sensory stimuli is able to become more apparent with the help of a strong and productive nervous system; this would include any change in emotion, memory or the environment. Neurons are known as the messengers of the body.…

neural impulse reaches the end of the axon, the neural impulse is now at the terminal button, also known as the axon bulb. The axon bulb contains many neurotransmitters. Neurotransmitters are chemicals that relay messages to another neuron between the synapses, the space between the axon bulb and the dendrites of another neuron. The synaptic gap does not come in contact with one another. The area where the neurotransmitters are released is called the presynaptic gap and the area where the…

release of neurotransmitters. Neurotransmitters are released from synaptic vesicles after they move down the axon and fuse across the cleft. This vesicle transport depends on the protein kinesin which moves synaptic vesicles down the axon to the synapse for release. The inability to move a vesicle down the axon will be kinesin related since kinesin is linked principally with organelles that travel in the anterograde direction on the axon (Nobutaka). The nematode C. elegans is a model…

How are humans, or any sentient life for that matter, anything more than complex arrangements of meat, neurons, and bone? The biophysical explanation of human physiology explains, quite in depth, the entire genetic makeup and biochemical arrangements from the simplicity of a ball and socket joint to the complexity of the brain. Surely the vast amount of research regarding human physiology could spearhead further research into the complexities of perception and thought, correct? There is no way…

up the neural transmission. When the electric pulse reaching the synapse terminal, a tiny junction between the axon of one neuron and another neuron, it stimulates the release of neural transmitters in form of synaptic vesicles. These neural transmitter vesicles will diffuse across the synapse space, and bind to the receptor sites on the receiving neurons either exciting or inhibiting the receptor neurons. The sending neuron synapse will reuptake the excessive amount of neural transmitter…

1. Why do you think fast axonal transport is important for synapses? Fast axonal transport is important for synapses because proteins are synthesized in the cell body and are transported down the axon by anterograde to the synaptic terminal. The proteins at the synaptic terminal which have reached the end of their lifetime are then transported back to the cell body by the retrograde transport for degradation and recycling. 2. Can depolarization occur without an action potential being created?…

Learning has the power to transform all of us. We have the opportunity to shape and mold our minds into learning whatever we desire. It wasn’t until my first semester of college that I learned what the six stages of learning are and how our emotions affect our learning. Emotion is the on and off switch for learning. It’s important for us to understand this process and how we learn biologically. Understanding how we learn can be the key to reaching our full potential and being…

more sentimental information such as the recognition of family members. There is not yet a cure for the disease however there are multiple drugs that assist in the inhibiting of acetylcholinesterase, an enzyme which inactivates acetylcholine at the synapse, preventing the normal breakdown of the neurotransmitter. (wisegeek.com) Dopamine Dopamine is neurotransmitter of the brain responsible for the proper usage of a variety of functions including movement, attention, learning, sleep as well as…
