Neurons in the brain communicate with each other through synapses, which are specialized connections between cells that allow for the transfer of information.

When neurons are activated in close proximity to each other, synapses between them can be strengthened through a process known as long-term potentiation (LTP), which involves changes in the strength and number of synaptic connections.

The brain also has mechanisms for "pruning" synaptic connections that are no longer needed or useful, which allows for more efficient information processing and storage.

The brain can make connections across different types of information, such as sensory information from the environment and memories stored in long-term storage.

Connections between neurons in the brain can be influenced by a variety of factors, including experience, genetics, and neural activity patterns. This means that the brain's connections are highly adaptable and can be shaped by both internal and external factors.
