The effects of stress on memory include interference with a person's capacity to encode memory and the ability to retrieve information. [1] [2] Stimuli, like stress, improved memory when it was related to learning the subject. [3] During times of stress, the body reacts by secreting stress hormones into the bloodstream.
Since the brain regions are so specialized in their functioning, damages done to specific areas of the brain can cause specific type of damage. Damage to the left side of the brain can lead to language discrepancies, i.e. difficulty in properly identifying letters, numbers and words, inability to incorporate visual stimuli to comprehend ...
Chronic stress has been shown to have negative impacts on the brain, especially in memory processing systems. [3] The hippocampus is vulnerable to repeated stress due to adrenal steroid stress hormones. [4] Elevated glucocorticoids, a class of adrenal steroid hormones, results in increased cortisol, a well known stress response hormone in the ...
Model of the Memory Process. Human memory is the process in which information and material is encoded, stored and retrieved in the brain. [1] Memory is a property of the central nervous system, with three different classifications: short-term, long-term and sensory memory. [2]
Besides memory, the amygdala also seems to be an important brain region involved in attentional and emotional processes. First, to define attention in cognitive terms, attention is the ability to focus on some stimuli while ignoring others. Thus, the amygdala seems to be an important structure in this ability.
The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals.It consists of nervous tissue and is typically located in the head (cephalization), usually near organs for special senses such as vision, hearing and olfaction.
The connectome will significantly increase our understanding of how functional brain states emerge from their underlying structural substrate, and will provide new mechanistic insights into how brain function is affected if this structural substrate is disrupted. [4] In his 2005 Ph.D. thesis, From diffusion MRI to brain connectomics, Hagmann wrote:
The dual-task n-back task is a variation that was proposed by Susanne Jaeggi et al. in 2003. [5] In the dual-task paradigm, two independent sequences are presented simultaneously, typically using different modalities of stimuli, such as one auditory and one visual.
