Which area of the brain produces new neurons?
Hippocampus is the area where new neurons are produced from the adult stem cells.
What Does the Limbic System Do?
The limbic system serves a variety of fundamental cognitive and emotional functions. The hippocampi, which lay on the inside edge of the temporal lobes, is essential to memory formation. The amygdalae sit on top of the front portion of each hippocampus. Each amygdala is thought to be important in processing emotion. The amygdala communicates closely with the hippocampus, which helps explain why we remember things that are more emotionally important. The amygdala also communicates closely with the hypothalamus, the area of the brain that is responsible for regulating temperature, appetite, and several other basic processes required for life. The hypothalamus itself is sometimes, but not always, included as part of the limbic system. Through the hypothalamus, as well as some key areas in the brainstem, the limbic system communicates with our autonomic nervous system (which regulates things like heartbeat and blood pressure), endocrine system, and the viscera (or “gut”).
Which structures are included in the limbic system?

The mammillary bodies and some thalamic nuclei are important to the formation of new memories. All of these pathways are intricately connected. The amygdala, for example, communicates to the orbitofrontal pathway through a white matter bundle called the uncinate fasciculus, as does the insula.
What is paralimbic in psychology?
From there, however, opinions diverge as to what is considered part of the limbic system, and what is paralimbic, meaning a structure that interacts closely with the limbic system but is not truly part of it.
Which part of the brain is responsible for communicating with the hippocampus?
The hippocampus largely communicates through a large white matter pathway called the fornix , which curves around the ventricles of the brain towards the mammillary bodies, sending out branches to the mammillary bodies, thalamus, and cingulate along the way. The limbic system is a heterogeneous group of structures and serves many different functions.
Which part of the brain is considered paralimbic?
The basal forebrain, nucleus accumbens, mammillary bodies and parts of the thalamus (the anterior and mediodorsal nuclei) are also often considered paralimbic structures due to their close interaction with the limbic system. Each of these paralimbic structures has been connected with emotion or basic cognitive processes.

The main components of the limbic system are the hippocampus, the amygdala, and the hypothalamus.
What is The Limbic System?
The limbic system describes several structures in the brain that are associated with emotion and memory processing, including the amygdala, the hippocampus, and the hypothalamus. These limbic system structures are also important in the response to stress by mediating how an organism responds to unpleasant or fearful stimuli.
What is the fearful stimulus that results in the amygdala sending signals to the hypothalamus?
A snake is a fearful stimulus that results in the amygdala sending signals to the hypothalamus for the fight or flight response.
How does amygdala damage affect memory?
Damage to the amygdala can cause a wide number of issues related to memory, emotion, sleep, appetite, and cognitive processing. One of the first key symptoms of amygdala damage is when a person is unable to make appropriate decisions, such that their decision-making skills are greatly impaired. Another symptom is memory loss since the loss of amygdala function can make it difficult for the brain to sort out which memories are emotionally important and which are not. Emotional processing is also greatly altered. Sometimes a person can become more "numb" to emotions and have a decreased fear response, for example, not reacting quickly to fearful stimuli. In other cases, the fear response is heightened tremendously which may cause anxiety and symptoms of paranoia.
What is the role of the amygdala in the brain?
The amygdala is particularly known for its role in fear and the processing of fearful stimuli. When exposed to fearful stimuli, such as a snake, the amygdala immediately sends this information to the hypothalamus to initiate a fight or flight response. Importantly, this form of communication is very quick and is another evolutionary tool that has been developed over time in order to avoid harmful situations.
Why is the hypothalamus important?
It is particularly important in the fight or flight response since it releases stress hormones and controls the body's response to fearful stimuli.
What is the role of the hippocampus in memory?
Since it has a key role in memory formation, damage to the hippocampus primarily affects the formation and recall of memories. Often, the first symptom of hippocampal damage is loss of spatial memory formation, whereby the injured person is incapable of remembering specific locations and directions. Damage to the hippocampus also results in the inability to recall episodic memories or form new ones, and this is best seen in diseases such as Dementia and Alzheimer's disease, epilepsy, and even depression.
What is the limbic system?

Which system is responsible for interpreting emotional responses, storing memories, and regulating hormones?
Thalamus: a large, dual lobed mass of gray matter cells that relay sensory signals to and from the spinal cord and the cerebrum. In summary, the limbic system is responsible for controlling various functions in the body. Some of these functions include interpreting emotional responses, storing memories, and regulating hormones.
Which part of the brain is responsible for long term storage?
Hippocampus: a tiny nub that acts as a memory indexer – sending memories out to the appropriate part of the cerebral hemisphere for long-term storage and retrieving them when necessary. Hypothalamus: about the size of a pearl, this structure directs a multitude of important functions.

The hippocampus is responsible for introducing what we learn into our long-term memory store.
What is the function of the amygdala?
Another essential function of the amygdala is to process fear in behavioral conditioning. That is to say, learning that a stimulus or environment is associated with some danger, so our body must prepare to defend itself.
What part of the brain is the amygdala located?
It is located in the middle part of the temporal lobe and communicates with the cerebral cortex, the hypothalamus, the septal area and the amygdala thanks to its multiple connections. Its most important task is to consolidate learning and memory.
Why is the hippocampus important?
In fact, it is essential for our spatial orientation and for identifying clues from the environment that are known to us.
Which part of the brain is in charge of learning and storing the implicit memories of fear?
Therefore, the amygdala would be in charge of learning and storing the implicit memories of fear (more unconscious); while the hippocampus would acquire declarative memories (those that can be consciously evoked).
What are the sensors that come from the body?
It has sensors that come from most of our body: olfactory system, retinas, viscera ... In addition to being able to capture temperature, glucose and sodium levels, hormonal levels, etc.
Which system is responsible for encoding social signals?
It has connections with areas of the limbic system such as the amygdala, thus taking charge of encoding data on social signals, and planning these interactions with others.
