Learning will increase the production of these new
neurons.
Yes, stress will decrease the production of new
neurons
in the hippocampus.
How about sex? Oh, wow! (Laughter) Yes, you are right, it will increase the production of new
neurons.
So this is one of the first studies that was carried out by one of my mentors, Rusty Gage from the Salk Institute, showing that the environment can have an impact on the production of new
neurons.
What you eat will have an effect on the production of new
neurons
in the hippocampus.
Omega-3 fatty acids, present in fatty fish, like salmon, will increase the production of these new
neurons.
However, not everything is lost; resveratrol, which is contained in red wine, has been shown to promote the survival of these new
neurons.
So we think that the effect of diet on mental health, on memory and mood, is actually mediated by the production of the new
neurons
in the hippocampus.
The first
neurons
came from jellyfish.
Although most people think of dopamine as the "happy" chemical of the brain, the dopamine-containing
neurons
in the basal ganglia die off in Parkinson's disease, that's what causes it.
That little guy contains almost half of the
neurons
in the entire brain.
And, of course, neuroscience, I've always been fascinated with neuroscience, but I never understood that I had to figure out why do the
neurons
fire, what about the environment helps us to learn, and all of those really contribute to making robots a little bit smarter.
Synesthetes inherit a biological propensity for hyperconnecting brain neurons, but then must be exposed to cultural artifacts, such as calendars, food names, and alphabets.
Scientists believe that this chameleon effect is possible because of a special set of
neurons
known as mirror
neurons.
Mirror
neurons
are a type of brain cell that responds equally when we perform an action as when we see someone else perform the same action.
These
neurons
are important for learning and self-awareness.
Neuroimaging studies using fMRI, functional magnetic resonance imaging, show us that when we seem someone yawn or even hear their yawn, a specific area of the brain housing these mirror
neurons
tends to light up, which, in turn, causes us to respond with the same action: a yawn!
Our psychological hypothesis also involves the work of these mirror
neurons.
Recently, neuroscientists have found that a subset of mirror
neurons
allows us to empathize with others' feelings at a deeper level.
The olfactory epithelium has a layer of olfactory receptor cells, special
neurons
that sense smells, like the taste buds of your nose.
It turns out that your brain has 40 million different olfactory receptor neurons, so odor A might trigger
neurons
3, 427, and 988, and odor B might trigger
neurons
8, 76, and 2,496,678.
Olfactory
neurons
are always fresh and ready for action.
But even though we've all got the same physiological set-up, two nostrils and millions of olfactory neurons, not everybody smells the same things.
Human ones weigh 1.5 kilograms, elephant brains 5 kg, and whale brains 9 kg, yet on a per weight basis, humans pack in more
neurons
than any other species.
There is a trade-off between body size and the number of
neurons
a primate, including us, can sustain.
A 25 kg ape has to eat 8 hours a day to uphold a brain with 53 billion
neurons.
Cooking frees up time and provides more energy than if we ate food stuffs raw and so we can sustain brains with 86 billion densely packed
neurons.
The high cost of maintaining resting potentials in all 86 billion
neurons
means that little energy is left to propel signals down axons and across synapses, the nerve discharges that actually get things done.
Even if only a tiny percentage of
neurons
fired in a given region at any one time, the energy burden of generating spikes over the entire brain would be unsustainable.
A drawback of sparse coding within a huge number of
neurons
is its cost.
