An event that is experienced from an 'out-of-body' perspective is remembered less well and its recall does not induce the usual pattern of hippocampal activation.
Olfactory receptors signal through G protein βγ subunits to silence the expression of other olfactory receptors within a single olfactory sensory neuron.
The period length of the circadian clock in the suprachiasmatic nucleus can be modulated by changes in DNA methylation induced by shortening the light–dark cycle.
In mice, the endocannabinoid system inhibits glutamatergic signalling from the olfactory cortex to the main olfactory bulb after fasting, increasing the detection of food odours and, consequently, enhancing food consumption.
The membrane lipid arachidonic acid is released from the postsynaptic neuron and can potentiate synaptic transmission by inhibiting presynaptic voltage-gated potassium channels.
A sufficient number of microglia must be present during postnatal development to ensure normal long-range connectivity and social behaviour in adulthood.
Fear extinction induces a shift in the balance of activity between 'fear neurons' and 'extinction neurons' in the basal amygdala, which project to prelimbic and infralimbic portions of the medial prefrontal cortex, respectively.
