The Memory Association
According to a 2004 research, the sense of smell is a complicated process.
- The olfactory receptor cells send a neuron signal to a part of our brain which is called the olfactory bulb.
- This multistep process which involves over a thousand genes and the nerves connect to the amygdala of the brain, the area responsible for processing emotions.
- It also connects to the memory and cognition area called the hippocampus, forming the association.
MORE IDEAS FROM THE ARTICLE
Certain smells that are associated in our minds to events or locations from the past, trigger our memories to revisit them. This association of the past through the sense of smell works better and is more vivid than the sense of touch or sight.
Example: Smelling the pages of a new book may remind us of late-night reading as a kid.
RELATED IDEAS
Recent studies suggest we employ the same neurophysiological mechanisms while dreaming that we use to construct and recall memories while we are awake.
Studies also found that vivid, bizarre and emotionally intense dreams are linked to parts of the amygdala and hippocampus. The amygdala plays a key role in processing and memory of emotional reactions. The hippocampus is implicated in important memory functions, such as the consolidation of information from short-term to long-term memory.
The whole brain can be considered an NCC because it generates experience continually.
- When parts of the cerebellum, the "little brain" underneath the back of the brain, are lost to a stroke or otherwise, patients may lose the ability to play the piano, for example. But they never lose any aspect of their consciousness. This is because the cerebellum is almost wholly a feed-forward circuit. There are no complex feedback loops.
- The spinal cord and the cerebellum are not enough to create consciousness. Available evidence suggests neocortical tissue in generating feelings.
- The next stages of processing are the broad set of cortical regions, collectively known as the posterior hot zone, that gives rise to conscious perception. In clinical sources of causal evidence, stimulating the posterior hot zone can trigger a diversity of distinct sensations and feelings.
- It appears that almost all conscious experiences have their origin in the posterior cortex. But it does not explain the crucial difference between the posterior regions and much of the prefrontal cortex, which does not directly contribute to subjective content.
- Humor has many practical uses, like diffusing a difficult situation, masking one’s nervousness, coping with failure and softening the criticism doled out to someone.
- Humor works well in social situations and helps people who are starting any relationship to build a bond.
- Funny people are perceived as attractive, smart and personable.
