Declarative Memory Analysis
We experience the process of thinking and our intentions as self-determining from our bodily functions. Conscious events are a reflection of our brains functions. Consciousness is the awareness of thoughts, perceptions, memories, and feelings. Memory is one of the most important functions we use every day. Characteristics of declarative memory as well as spatial memory and long term memory all have a role in the hippocampus. Also responsible for our memory, ageing and dementia is acetylcholine.

Declarative memory is the storage and conscious recollection of events occurring in a particular place and time. Declarative memory involved the ability to form associations and retain relational information across time. Facts and events are able …show more content…
Long term Potentiation also known as LTP is the leading model of synaptic changes that underlie learning and memory. This occurs when the synapse is active and the postsynaptic cell is depolarized. Cells that lead to the synapse onto the dentate granular cells are called DG cells which then send axons to CA3. CA3 cells are responsible for sending axons to CA1 output cells. LTP has four crucial steps to making the process obtainable. One glutamate the neurotransmitter to the CNS is released allowing acts on both AMPA and NMDA receptors. Sodium receptors are then able to flow through the AMPA. Next the depolarization of postsynaptic cells relieve the MG2 block to the NMDA. This allows sodium and calcium to flow to the dendritic spine. Thirdly the increase of calcium binds to calmodulin to activate calmodulin kinase which then undergoes autophosphorylation. Which means they become more sensitive to glutamate and promotes movement to the AMPA receptors. Lastly the entry of calcium activates PK which phosphorylates to CREB, resulting in nitic oxide synthase. This means no synthesis is produced, and the presynaptic terminal facilitates glutamate release. The increase of glutamate and AMPA result in a faster and stronger …show more content…
The role of acetylcholine (ACh) is the first identified neurotransmitter. This means when Ach is released into the hippocampus this allows for a electrical signal to go to the brain being called hippocampus theta. Hippocampus theta occurs during exploration or investigation behavior. Theta activity is processed to the dentate gyrus and CA3 field allowing information to be sent to the CA1 field. During a deep sleep the CA1 information is transferred to the neocortex where long term memories can be

    Acetycholine & Black Widow Bite

    Acetylcholine better known as ACh is a neurotransmitter that is produced by cholinergic neurons. Nerves that rely on Ach are classified as cholinergic nerves. Acetylcholine is found in both the peripheral nervous system and the central nervous system. Acetylcholine can also be found in the autonomic nervous system and is the only neurotransmitter used in motor division of the somatic nervous system. In the peripheral nervous system acetylcholine plays a role in skeletal muscle movement, as well as in the regulation of smooth muscle and cardiac muscle. In the central nervous system acetylcholine is believed to be involved in the sleep-wake cycle, learning, memory, and mood.…

    Glutamate Research Paper

    Glutamate is one of the main excitatory neurotransmitter in the dominant nervous structure. Glutamate performs on 4 diverse post synaptic receptors; NMDA (N-Methyl-D-aspartate) AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid), Kainate and metabotropic receptors. The three previous receptors are related to membrane ion channels whereas metabotropic receptors are coupled with a G protein. Glutamate is intricated in the physiologic procedures of learning, remembrance and motricity. Glutamate is also a potent neurotoxin accountable for toxic neuronal decease of post synaptic neurons. This action has been denominated excitotoxicity and happens as a result of a long or a strong triggering of glutamate post-synaptic receptors. The…

    Muscle Contraction/Excitation

    (1)The action potential travels down the somatic motor neuron axon reaching the synaptic bulb causing calcium ions to flow into the synaptic bulb. (2)The increase of calcium in the synaptic bulb causes the synaptic vesicles to undergo exocytosis. (Exocytosis a process that allows large molecule to leave the cell without actually passing through the plasma membrane) It then spits out the contents which is Acetylcholine (ACh) (3) ACh is then released into the synaptic cleft. (4)ACh diffuse across the cleft and binds with the receptors on the motor end plate, known as sarcolemma which is a muscle fiber that mirrors the synaptic bulb. (5)ACh grabs onto the receptor causing Na+ to enter the muscle fiber. This also allows K+ to exit the muscle fiber which causes depolarization and the production of an action potential.…

    Essay On Procedural Memory

    Memory is such an intricate part of our brain. Memory allows us to learn, recall, and store important life events. Memory is “the mental capacity or faculty of retaining and reviving facts, events, impressions, etc., or of recalling or recognizing previous experiences.” (Dictionary) Memory holds valuable information that has made an impression in some way or another. Just like our mind, memory is composed of multiple systems. The 4 most common systems are declarative, episodic, procedural and mental imagery. Episodic memory is memory from personal experiences, or memory that we see from our own point of view. Declarative is memory of facts, stuff that is true. This system is particular used for school, to remember items needed for tests, papers, etc. Procedural Memory is how we do things, like remembering how to cook or how to get somewhere. And finally, mental imagery, which I remember how things looked, like the shirt I wore yesterday was…

    The means by which the brain performs are referred to as neuroprocesses, which are related to learning and memory. The brain is the center of every function of the body that controls functional learning and memory and how the two are interdependent. Learning occurs when the memory is stimulated. The memory is activated once learning has taken place. With knowledge at the center of attention, it is imperative to stimulate the brain through lifelong learning to achieve longevity and quality of life.…

    Intellectual Disability

    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 influx of calcium ions. In this way, NMDA activation functions as a coincidence detector, indicating simultaneous activity by the pre- and post-synaptic cell. The calcium flow caused by this process triggers cellular processes that enhance the signaling strength between the two cells: added receptors, larger synaptic surface area, and so forth. Matsuzaki and colleagues (2004) investigated the process of LTP on dendritic spines in the hippocampus, a brain structure particularly involved in memory. When NMDA receptors on a spine are activated, the spine grows in size. This enlargement may be permanent and is subsequently associated with greater signal strength from the pre-synaptic cell. Spine pathology, then, may disrupt LTP responses in individuals with intellectual…

    Psychology - Memory

    In psychology, memory is an organism's ability to store, retain, and recall information and experiences. Traditional studies of memory began in the fields of philosophy, including techniques of artificially enhancing memory. During the late nineteenth and early twentieth century, scientists have put memory within the example of cognitive psychology. In recent decades, it has become one of the principal pillars of a branch of science called cognitive neuroscience, an interdisciplinary link between cognitive psychology and neuroscience.…

    Memory

    Memory is defined as the persistence of learning over time through the storage and retrieval of information. Memory is a vital tool in learning and thinking process. We use memory in our everyday lives. I think about the first time I drove a school bus; that is a form of memory. If we do not remember anything from the past, we would never learn from our experiences. Without memories, we are exposed to unfamiliar things. Memory is viewed as a three-stage process, which include sensory memory, short-term memory, and long-term memory.…
