What is considered "unique" about the hypothalamus as compared to other brain structures?
Cells of hypothalamus act directly as their own sensory organs
- The hypothalamus has inputs and outputs with both neural and non-neural (e.g. humoral; physical stimuli) sources
- inputs: neural and non-neural (e.g. humoral, physical stimuli)
- outputs: neural and non-neural (e.g. neuroendocrine outputs)
for physical stimuli arising from the internal environment (visceral information) such as temp/hormone levels
part of hypothalamus resides outside of blood brain barrier (i.e. circumventricular organ system)
some hypothalamus axons synapse directly on blood vessels (i.e. neuroendocrine outputs)
