The nervous system consists of the central nervous system (brain and spinal cord) and the peripheral nervous system (motor nerves, sensory nerves, cranial and spinal nerves, autonomic ganglia, and plexuses).
Certain neurons encode memories of events that occurred in specific physical locations known as place fields. Chickadees show patterns of neuronal activity that are specific to locations of hidden food but independent of place fields.
Artificial neural networks that model the visual system of a male fruit fly can accurately predict the insect’s behaviour in response to seeing a potential mate — paving the way for the building of more complex models of brain circuits.
Neuroscientists find that two distinct neural pathways are responsible for the addictive properties of the opioid fentanyl: one mediates reward, the other promotes the seeking of relief from symptoms of withdrawal.
By combining advanced mathematical modelling with data from a rare sample of patients with brain damage, the authors show that a specific part of the brain in the ventromedial prefrontal cortex is associated with putting in effort to help other people.

Long-term memories are thought to be represented by the same brain areas as those that encode sensory stimuli, but the mechanisms remain unclear. A study that recorded neural activity from face-selective regions of the macaque brain found that these regions represent familiar faces using a neural code that is distinct from the one for sensory representation.
