Plasticity and by
Plasticity is vital for coking as it represents its ability to gradually form specific plasticity phases during the coking process, measured by coal dilatation tests.
Plasticity in a crystal of pure metal is primarily caused by two modes of deformation in the crystal lattice, slip and twinning.
* Synaptic Plasticity, Neuroscience Online ( electronic neuroscience textbook by UT Houston Medical School )
Plasticity and .
* Plasticity is the behaviour observed after the material is subjected to a yield stress :</ br > A material that behaves as a solid under low applied stresses may start to flow above a certain level of stress, called the yield stress of the material.
* Plasticity or plastic deformation is the opposite of elastic deformation and is defined as unrecoverable strain.
Plasticity can be categorized as short-term, lasting a few seconds or less, or long-term, which lasts from minutes to hours.
Plasticity in female choice is favored for adapting to changes in ecological and social environments.
Plasticity surface friction is also very low in comparison to the plastic deformation energy and can be neglected.
Plasticity of the brain is when rewiring occurs because of brain damage, finding different neural pathways and not relying on the damaged structures.
memory and formation
Increased neural activity at spines increases their size and conduction which is thought to play a role in learning and memory formation.
The lateral Prefrontal cortex ( PFC ) is essential for remembering contextual details of an experience rather than for memory formation.
The regions of the Diencephalon have shown brain activation when a remote memory is being recovered and the Occipital lobe, Ventral Temporal lobe, and Fusiform gyrus all play a role in memory formation.
The EC-hippocampus system plays an important role in autobiographical / declarative / episodic memories and in particular spatial memories including memory formation, memory consolidation, and memory optimization in sleep.
The subsequent abnormalities in the formation and function of synapses and development of neural circuits result in impaired neuroplasticity, an integral part of memory and learning.
Psychologists and neuroscientists generally agree that the hippocampus has an important role in the formation of new memories about experienced events ( episodic or autobiographical memory ).
The dorsal region of the hippocampal formation serves for spatial memory, verbal memory, and learning of conceptual information.
" Tillemont, possibly influenced by the fact that no honour is paid to the memory of Nicolas by any branch of the Church, allows more weight to the testimony against him ; rejects peremptorily Cassian's statement — to which Neander gives his adhesion — that some other Nicolas was the founder of the sect ; and concludes that if not the actual founder, he was so unfortunate as to give occasion to the formation of the sect, by his indiscreet speaking.
Reduction in formation of new long-term memory ( which by definition survives withdrawal of attention ), is common in delirium, because initial formation of ( new ) long-term memories generally requires an even higher degree of attention than do short-term memory tasks.
The psychological internalization of territorial and dominance experiences in conscious and unconscious memory are established through the formation of social identity, personal identity, body concept, or self concept.
Indeed, there is evidence that while episodic memory is reliant on the hippocampal formation, amnesiacs with damage to this area can show a loss of episodic memory accompanied by ( partially ) intact semantic memory.
memory and amygdala
Recent studies of patients with damage to the amygdala suggest that it is involved in memory for general knowledge, and not for specific information.
In the study of declarative memory, the hippocampus and the amygdala are two structures frequently examined using this technique.
-Sensory cortex organizes information for dissemination to hypothalamus ( fight or flight ), amygdala ( fear ), hippocampus ( memory )
Recent studies suggest that, while the amygdala is not itself a long-term memory storage site, and learning can occur without it, one of its roles is to regulate memory consolidation in other brain regions.
Also, fear conditioning, a type of memory that is impaired following amygdala damage, is mediated in part by long-term potentiation.
The regions of the brain involved in memory processing that are implicated in PTSD include the hippocampus, amygdala and frontal cortex.
Investigations into the amygdala revealed " people who showed strong amygdala activation in response to a set of positive or negative stimuli ( relative to other study participants ) also showed superior memory for those stimuli ( relative to other study participants )" ( Kensinger, 2007 ).
When viewing emotional content, research has shown that men enhance their memory by activating their right amygdala while women activate the left side ( Kensinger, 2007 ).
This experiment found that " previously reported sex differences of memory associations with left amygdala for women and with right amygdala for men were confined to the ventral amygdala during picture viewing and delayed memory " ( Makiewicz, 2006 ).
Although it is still unclear how lateralization affects memory, there may be a more effective relationship between activation of the left amygdala and memory than activation of right and memory.
Since the role of the amygdala in memory is associated with increased arousal induced by the emotional event, factors that influence arousal should also influence the nature of these memories.
