SEGMENTATION WITH NEURAL NETWORK B.Prasanna Rahul Radhakrishnan Valliammai Engineering College Valliammai Engineering College prakrish_2001@yahoo.com krish_rahul_1812@yahoo.com Abstract: Our paper work is on Segmentation by Neural networks. Neural networks computation offers a wide range of different algorithms for both unsupervised clustering (UC) and supervised classification (SC). In this paper we approached an algorithmic method that aims to

ions move into or out of the neuron through these channels? Into 5. Voltage-gated potassium channels open at what voltage? -130 mV 6. Acetylcholine (ACh) and GABA are neurotransmitters that open chemically-gated channels. What ions pass into the cell when these channels are activated? a. ACh: Sodium (Na+) ions b. GABA: Chlorine (Cl-) ions 7. Ion channels are regionally located and functionally unique. List all the areas on the neuron and the type of potential dependent

Neuroscientists do not have an answer as to how the brain of a worm processes information. A worm has a mere few hundred neurons‚ to our approximately one-hundred billion. This a true testament to how far we have to go in neuroscience but also to how

Spines play an essential role in long term-potentiation‚ the process by which activity between synapsing neurons strengthens their connection. LTP occurs when glutamate released by a pre-synaptic neuron binds to an NMDA receptor on the post-synaptic cell (Lynch‚ 2004). If the post-synaptic cell is sufficiently depolarized at this time‚ a magnesium ion will be expelled from the channel‚ allowing for an

* Nervous Tissue: The Basic Hardware * Neurons are individual cells in the nervous system that receive‚ integrate‚ and transmit information. * The soma‚ or cell body‚ contains the cell nucleus and much of the chemical machinery common to most cells. * Dendrites are the parts of a neuron that are specialized to receive information. * The axon is a long‚ thin fiber that transmits signals away from the soma to other neurons or to muscles or glands. * The axon ends
