Post-hatch neuron incorporation in the zebra finch caudomedial nidopallium (NCM) in relation to vocal learning
The songbird telencephalon continually receives new neurons. Peak levels of neuron addition in singing-related areas have been associated with maximal vocal learning. The caudomedial nidopallium (NCM), analogous to mammalian auditory association cortex, is a crucial brain region for acquiring tutor song memory. NCM contains a high number of inhibitory interneurons, including parvalbumin-express...
متن کاملVocal control neuron incorporation decreases with age in the adult zebra finch.
In adult male zebra finches, high vocal center (HVC) neurons continuously die and are replaced. Many of these cells are projection neurons that form part of the efferent pathway controlling learned song production. Although it is known that HVC receives new neurons well into adulthood, it is unknown whether this occurs at a constant rate or declines with adult age. We used [3H]thymidine to labe...
متن کاملThe hippocampus and caudomedial neostriatum show selective responsiveness to conspecific song in the female zebra finch.
The perception of song is vital to the reproductive success of both male and female songbirds. Several neural structures underlying this perception have been identified by examining expression of immediate early genes (IEGs) following the presentation of conspecific or heterospecific song. In the few avian species investigated, areas outside of the circuit for song production contain neurons th...
متن کاملFOS and ZENK responses in 45-day-old zebra finches vary with auditory stimulus and brain region, but not sex.
Male zebra finches (Taeniopygia guttata) begin to sing around 45 days posthatch (d45) and tune their songs to match learned templates. Females never develop song, but they use male conspecific vocalizations for mate choice. While auditory perception is critical for both sexes, the responses of the immediate early genes (IEGs) ZENK and FOS differ in auditory brain areas of d30 males and females....
متن کاملBirdsong Memory: A Neural Dissociation between Song Recognition and Production
Songbirds learn their song from an adult conspecific tutor when they are young, much like the acquisition of speech in human infants. When an adult zebra finch is re-exposed to its tutor's song, there is increased neuronal activation in the caudomedial nidopallium (NCM), the songbird equivalent of the auditory association cortex. This neuronal activation is related to the fidelity of song imita...
