The hypothalamus of the adult ring dove contains acoustic units that respond to species-specific coo vocalization. Loss of nest coo leads to unsuccessful breeding. However, the recovery of nest coo in some doves suggests that these units are capable of self-renewal. We have previously shown that lesioning the hypothalamus generates the addition of new neurons at the lesioned area. In this study, we sought to determine whether lesion-induced new neurons are involved in the recovery of coo…

Lesion-induced neurogenesis in the hypothalamus is involved in behavioral recovery in adult ring doves.
TLDR
Investigating whether lesion-induced newborn neurons in the VMN facilitate the recovery of courtship behavior in the lesioned birds found that a social factor, that is, when the male doves were cohoused with a mate, facilitated neurogenesis and behavioral recovery.
Nest of Origin Predicts Adult Neuron Addition Rates in the Vocal Control System of the Zebra Finch
TLDR
Variation in genotype and/or early pre- or postnatal experience can account for a large fraction of adult variation in rates of neuron addition and it is suggested that a major constraint on neurogenesis and the capacity to adjust rates of neurons addition in response to adult auditory experience is established early in development.

Bilateral neurotoxic lesions in NCM before tutoring onset do not prevent successful tutor song learning
TLDR
Surprisingly, NCM-lesioned juveniles successfully copied the tutor song at least as well as untreated control animals, showing that a fully intact NCM is not required for tutor song memory formation and normal song development.
Adult Neurogenesis in Injury-Induced Self-Repair: Use It or Lose It
TLDR
Evidence from ring dove studies is presented that an activity-dependent mechanism underlies the survival of adult newborn neurons and establishment of their functionality and collective behavioral analyses of social stimulations suggest that sensorimotor events contribute to the integration of new neurons and reinstatement of function.
Inhibition of lesion-induced neurogenesis impaired behavioral recovery in adult ring doves
Beyond the Hippocampus and the SVZ: Adult Neurogenesis Throughout the Brain
TLDR
Evidence in support of the classic and novel neurogenic zones present within the mammalian brain are summarized and the functional significance of these new neurons as well as the factors that regulate their production are discussed.
Neuroendocrine regulation of vocalizations and other sounds in nonsongbirds
Birds as a model to study adult neurogenesis: bridging evolutionary, comparative and neuroethological approaches
TLDR
This review describes adult avian neurogenesis and neuronal recruitment, discusses factors that regulate these processes, and touches upon the question of their genetic control.

Hypothalamic Neurons Preferentially Respond to Female Nest Coo Stimulation: Demonstration of Direct Acoustic Stimulation of Luteinizing Hormone Release
TLDR
Observed feature-detecting neurons such as the female-nest-coo-specific units are involved in gonadotropin-releasing hormone output, suggesting that female nest coos mediate ovarian growth.

TLDR
It is concluded that neuronal precursors exist in the HVc ventricular zone that incorporate tritiated thymidine during the S phase preceding their mitosis; after division these cells migrate into, and to some extent beyond, HVm, which seems to be a normally occurring phenomenon in intact adult female canaries.
Birth, migration, incorporation, and death of vocal control neurons in adult songbirds.
TLDR
The unexpected large-scale production of neurons in the adult brain holds important clues about brain function and, in particular, about the neural control of a learned behavior--birdsong.
A relationship between behavior, neurotrophin expression, and new neuron survival.
TLDR
It is shown that singing enhances mRNA and protein expression of brain-derived neurotrophic factor (BDNF) in the HVC of adult male canaries, Serinus canaria, and the increased BDNF expression is proportional to the number of songs produced per unit time.
Cell death and neuronal recruitment in the high vocal center of adult male canaries are temporally related to changes in song.
TLDR
It is suggested that seasonal peaks in cell loss and neuronal recruitment in HVC are related to endocrine changes and that all three play a role in the seasonality of song modification.
Neurons generated in the adult brain are recruited into functional circuits.
TLDR
Of the 74 neurons labeled with horseradish peroxidase that were recovered, the nuclei of seven neurons were radioactively labeled and apparently generated during or after the 3H-labeled thymidine treatment (during adulthood) and subsequently incorporated into functional neural circuits.

TLDR
A pronounced loss and replacement of neurons implicated in vocal control during this period may relate to the canary's ability to modify song in adulthood, raising the possibility that much if not all of the pathway from HVC to RA is replaced within a year.
Induction of neurogenesis in the neocortex of adult mice
TLDR
It is shown that endogenous neural precursors can be induced in situ to differentiate into mature neurons, in regions of adult mammalian neocortex that do not normally undergo any neurogenesis.
Neurogenesis in the adult is involved in the formation of trace memories
TLDR
It is shown that a substantial reduction in the number of newly generated neurons in the adult rat impairs hippocampal-dependent trace conditioning, a task in which an animal must associate stimuli that are separated in time.
