Nettet18. sep. 2024 · It is only in the last decade that researchers have shown that new neurons are born in the hippocampus in the human brain throughout life. In the most conclusive study, researchers used a carbon-dating technique to accurately determine the age of individual cells within the hippocampus.
Nettet15. mai 2024 · Neurons are cells in the brain. Neurons use both electrical charges and chemicals called ions to communicate with each other. We say that neurons have an electrochemical charge, and this charge changes, depending on whether the neuron is at rest or is sending a signal. my wifi connection has disappearedNettet6. jan. 2024 · In the first part of the article, we introduce computational neuroscience in brief which include, the role that neurons play, the anatomy of the neurons and the models that could be explained for the functionalities of the brain, so called, the brain models.
