The adult human brain has approximately 86 billion neurons and an average of 7,000 synapses per neuron, resulting in a total synaptic count exceeding 6 × 10^14.
The human brain accounts for 2% of body weight but uses 20% of the body's oxygen at rest.
Over 80% of the brain's neurons are located in the cerebellum.
Hippocampal damage leads to anterograde amnesia for new episodic memories and does not impair skill learning or retrograde memories from early life.
Humans use only 10% of their brain at any one time.
The human brain does not generate new neurons in adulthood.
Adult neurogenesis occurs in the human neocortex.
The correlation between human brain volume and intelligence is r = 0.4.
Daily mindfulness meditation for 10 minutes increases hippocampal volume by at least 1% within one month.
The superior method for enhancing neuroplasticity in adults is neurofeedback training compared to exercise or sleep optimization.
