All About the Different Types of Amnesia. Everything you need to know about your brain. Among other things, the monkeys became more docile and seemed to display little fear. The constellation of behavior that resulted from amygdalae removal was called Kluver-Bucy syndrome , and it led to the amygdala being investigated for its role in fear.

Since, the amygdala has become best known for its role in fear processing. When we are exposed to a fearful stimulus, information about that stimulus is immediately sent to the amygdala, which can then send signals to areas of the brain like the hypothalamus to trigger a " fight-or-flight " response e.

There is a pathway that runs from the thalamus to the amygdala, and sensory information about fearful stimuli may be sent along this pathway to the amygdala before it is consciously processed by the cerebral cortex. This type of reflexive response can be useful if we really are in great danger. For example, if you are walking through the grass and a snake darts out at you, you don't want to have to spend a lot of time cognitively assessing the danger the snake might pose.

Instead, you want your body to experience immediate fear and jump backward without having to consciously initiate this action. The direct pathway from the thalamus to the amygdala may be one way to achieve this type of response. In addition to its involvement in the initiation of a fear response, the amygdala also seems to be very important in forming memories that are associated with fear-inducing events.

For example, if you take mice with intact amygdalae and play a tone right before you give them an uncomfortable foot shock, they will very quickly begin to associate the tone with the unpleasant shock. Thus, they will display a fear reaction e. But the key here is we still have a lot to figure out before we can pursue it as a way of helping people with memory impairments. Predicting the path of illness for someone diagnosed with schizophrenia is difficult because its origins are so varied.

Dana Grantee Jong Yoon is developing imaging methods to tease out the cellular mechanisms of one potential cause: too much dopamine production. Using a machine learning model, researchers describe how excessive worrying can accelerate brain aging and cognitive decline. Two reports suggest that neuromyths are more pervasive in the educational community than we might think, and this may work against academic achievement.

We investigate some of the most common myths, explaining their scientific origins and realities. What is attachment and how does it form?

By imaging individual cells in the brains of prairie voles, Dana Foundation Grantee Zoe Donaldson's lab has identified a neural network that signals how strong their preference for their partner is.
