This echoic memory storage involves several different brain areas, due to the different processes it is involved in. The majority of brain regions involved are located in the prefrontal cortex as this is where the executive control is located, [ 10 ] and is responsible for attentional control.
The Heschl's gyrus/transverse temporal gyrus includes Wernicke's area and functionality, it is heavily involved in emotion-sound, emotion-facial-expression, and sound-memory processes. The entorhinal cortex is the part of the 'hippocampus system' that aids and stores visual and auditory memories.
The entorhinal cortex (EC) is an area of the brain's allocortex, located in the medial temporal lobe, whose functions include being a widespread network hub for memory, navigation, and the perception of time. [1] The EC is the main interface between the hippocampus and neocortex.
The belt is the area immediately surrounding the core; the parabelt is adjacent to the lateral side of the belt. [6] Besides receiving input from the ears via lower parts of the auditory system, it also transmits signals back to these areas and is interconnected with other parts of the cerebral cortex.
The impulse propagates across the auditosensory area, the auditopsychic area and eventually the entire temporal lobe. Therefore, this allows the formation of memory and comprehension of sound to take place. The posterior auditopsychic region has a site especially for an understanding of speech called the Wernicke's area (Brodmann area 22).
“It’s normal for things like our speed of thinking and recall of names to slow down.” Alzheimer’s-related memory loss is more than just not being able to remember someone’s name.
Memory lapses like these are common for people of all ages. “Mild forgetfulness — you forget somebody’s name or where you left something — that’s totally normal,” says Karlene Ball, Ph.D.
In humans, the ear is described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the auricle and the ear canal . Since the outer ear is the only visible portion of the ear, the word "ear" often refers to the external part (auricle) alone. [ 1 ]
