Neurotransmitter Switching? No Surprise
Among the many forms of brain plasticity, changes in synaptic strength and changes in synapse number are particularly prominent. However, evidence for neurotransmitter respecification or switching has been accumulating steadily, both in the developing nervous system and in the adult brain, with observations of transmitter addition, loss, or replacement of one transmitter with another. Natural s...
متن کاملSurprise ! ! No make - up classes !
Notre Dame and St. Mary's stu~dents will not have to make up class days missed as a result of the blizzard which began last Wednesday night and crippled much of the midwest. The announcement came yesterday as a joint decision from Fr. Ferdinand Brown, acting provost at Notre Dame, and Dr. James Duggan, St. Mary's president. Notre Dame announced yesterday that classes will resumf' today. St. Mar...

متن کاملNeurotransmitter Switching Regulated by miRNAs Controls Changes in Social Preference.
Changes in social preference of amphibian larvae result from sustained exposure to kinship odorants. To understand the molecular and cellular mechanisms of this neuroplasticity, we investigated the effects of olfactory system activation on neurotransmitter (NT) expression in accessory olfactory bulb (AOB) interneurons during development. We show that protracted exposure to kin or non-kin odoran...
متن کاملNeurotransmitter switching in the adult brain regulates behavior.
Neurotransmitters have been thought to be fixed throughout life, but whether sensory stimuli alter behaviorally relevant transmitter expression in the mature brain is unknown. We found that populations of interneurons in the adult rat hypothalamus switched between dopamine and somatostatin expression in response to exposure to short- and long-day photoperiods. Changes in postsynaptic dopamine r...
