🗑
|
||||
| show | a neurotransmitter that is involved in the transmission of pain messages in the brain
🗑
|
||||
| show | the theory that pain is a product of both physiological and psychological factors that cause spinal gates to open and relay patterns of intense stimulation to the brain, which perceives them as pain

||||

|
||||
| vestibular sense | show 🗑
|

|
||||
| show | Many objects in the photograph are partially obscured by other objects-such as trees. In each case, the object that is not obscured is perceived as being closer
🗑
