Perception -- the conscious perception of sensory inputs, the conscious appreciation of sensory inputs -- depends entirely on the forebrain.
The conscious appreciation of sensory inputs depends on the cerebral cortex.

Homeostasis is a distributed process, which depends on forebrain, brain stem and spinal chord.
The contribution of forebrain to homeostasis is hormonal. The contribution of brain stem is through autonomic changes (changes we are not consciously in control of) as well as through consciously made movements.
Same is true for spinal chord.

Higher Abstract Functions depend entirely on forebrain.

There's only one type of neurons that leaves the central nervous system (CNS) and goes directly to muscles, and that's the motor neuron.
There are a hundred thousand out of 200B neurons in the CNS.
The motor neurons are contained either in the brain stem or in the spinal chord. But, there are no motor neurons in the forebrain.

The good news: Just as a collapse in one part of an ecosystem can ripple out, lifting the health of a species or community could also benefit the whole. https://t.co/fVLRXwgsfA

So, I recently got interested in neuroscience and decided to learn more. Having had no formal training in neurobiology before, I just registered for this course on Coursera.

This morning, the Moon is stepping in front of Mars. This occlusion, Mars-and-the-Moon, occurs twice a year. It’s kind of like an eclipse, but an eclipse is a specific kind of occlusion where a shadow is cast.
