Action potential

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…

All of our feelings, sensations, motor, thoughts and emotional responses, learning and memory, the actions of mind-blowing medicine, the causes of mental disorders, and the other perform or pathology of the human brain cannot be understood while not the data regarding the fascinating method of communication between nerve cells. Neurons should unendingly gather data regarding the interior state of the organism and its external setting, appraise this data, and coordinate activities acceptable to…

The nervous system is composed of two main parts which are the central nervous system and the peripheral nervous system. The central nervous system includes the brain and nerve cords like the spinal cord while the peripheral nervous system includes the motor nerves and sensory nerves. There are two main types of support cells in the nervous system which are glial cells and neurons. The neurons' function in the system is to receive and send electrical signals. The glial cells provide insulation…

in forming ontogenetic columns. This article is important to the general educated audience because it presents basic rules in which guide neural connectivity in the neocortex. The sister neurons become electrically coupled, which is a spread of potential change from one cell to another, by current flow through gap junctions, the region of contact between two cells. This is done during the postnatal period of the cortex, which also revealed correlated spiking activity in brain slices. Afterwards,…

there is the brain. The brain is the control focal point of the human body. The human brain stores data, corresponding that data with other data to offer the body some assistance with making selections and to have the body put the decisions into actions. The brain and spinal cord are created from the neural tube. The neural tube then extends causing the tube to then makes three locales called the primary brain vesicles: prosencephalon, mesencephalon, and the rhombencephalon. The prosencephalon…

Lafora disease is a rare, inevitably fatal, autosomal recessive, progressive myoclonus epilepsy. Being autosomal recessive, the disease is most commonly seen in communities that practice consanguinity. The onset of the disease occurs within the first two decades of life, with an average life span of 10 years following diagnosis (Monaghan & Delanty, 2010). Lafora disease is characterized by myoclonic and tonic-clonic seizures and neurological dysfunction, such as dementia (Monaghan & Delanty,…

Neuronal regeneration is a high energy demanding process however, with maturation, axonal mitochondria transport progressively declines. Mitochondria are cellular powerhouses that supply ATP; essential for neuron growth, survival, and regeneration. Motile mitochondria can become stationary and in mature axons of the central nervous system (CNS), the majority of the mitochondria become stationary with only about 20-30% remaining motile. With this reduction in mitochondrial transport, mature CNS…

INTRODUCTION Alzheimer’s disease is a progressive neurodegenerative disorder characterized by memory loss and dementia. The neurodegeneration is due to a formation of amyloid platelets in the brain that interrupt the normal function of it. It worsen with the pass of years and is mostly suffered by older people (Reece et al. 2014). The platelets composed by Amyloid; a harmful insoluble protein fibril which is produced by Amyloid precursor protein (APP). APP is processed in the membrane of neurons…

Estimating the speed of neural transmission from hand-ankle (treatment A) and hand-hand (treatment B) Introduction A neuron is a specialised cell transmitting nerve impulses and its function is to transmit information within the nervous system which is a network of nerve cells and fibres which transmit nerve impulses between parts of the body. Neural transmission occurs when a neuron is activated (sends out an electrical impulse). Activation of a neuron takes place when the neuron is stimulated…

Potassium channels (KC) are selective transmembrane proteins that allow K+ ions flow down an electrochemical gradient across cell membrane, thus controlling plasma membrane potential in both excitable and non-excitable cells (Szabo, Zoratti&Gulbins, 2010). Evolutionarily conserved KC family is one of the larges and most diverse of ion channels (Table1). Its diversity comes not only from a large number of genes coding for main subunits (over 80 mammalian genes). Many other processes such as…
