Intrinsic and synaptic properties of neurons in the vocal-control nucleus lMAN fromin vitro slice preparations of juvenile and adult zebra finches

Abstract: A common theme of diverse neural systems is that circuits that are important for initial acquisition of learning do not necessarily serve as a substrate for the long‐term storage of that memory. The neural basis of vocal learning in songbirds provides an example of this phenomenon, since a circuit that is necessary for vocal production during initial stages of vocal development apparently plays no subsequent role in controlling learned vocalizations. This striking functional change suggests the possibility of … Show more

“…LMAN’s core region contains magnocellular neurons that send dual projections to Area X and RA, as well as GABAergic neurons that influence the projection neurons through inhibition [62,63]. The magnocellular neurons are of particular interest since they provide direct input to the AFP via Area X, and the DMP via RA.…”

“…Consistent with this, the presence of functional GABA type A (GABA A ) receptors, within the song system, has been 6 demonstrated electrophysiologically by a number of groups (Livingston and Mooney, 1997;Bottjer et al, 1998;Luo and Perkel, 1999;Vicario and Raksin, 2000;Pinaud et al, 2004;Farries et al, 2005;Mooney and Prather, 2005), although a detailed pharmacological characterisation is lacking. For example, picrotoxin and bicuculline block receptors on neurons within the LMAN (Livingston and Mooney, 1997;Bottjer et al, 1998), the DLM (Luo and Perkel, 1999), the HVC (Mooney and Prather, 2005), the RA (Vicario and Raksin, 2000) and Area X (Farries et al, 2005). From this body of work, it appears that GABA A receptors, which are a family of post-synaptic proteins, play an important role in the learning and production of song in the zebra finch.…”

“…A significant body of literature has strongly implicated GABA A receptors in the regulation of excitation within the zebra finch song system (Livingston and Mooney, 1997;Bottjer et al, 1998;Luo and Perkel, 1999;Cardin and Schmidt, 2004;Pinaud et al, 2004;Farries et al, 2005;Mooney and Prather, 2005). These receptors are the major inhibitory neurotransmitter receptors in brain, and they exist in a variety of forms called subtypes, that are assembled from seven different types of subunit (, , , , ,  and ; Darlison et al, 2005;Sieghart, 2006).…”

“…Prior literature suggests that a substantial portion of the spikes we recorded was from excitatory projection neurons. First, for LMAN, the ratio of projection neurons to interneurons has been estimated at around 3:1 ( Bottjer et al, 1998 ) to 15:1 ( Livingston and Mooney, 1997 ). Further evidence that excitatory neurons are more easily detected than inhibitory ones comes from reports of difficulty finding interneurons in slice preparations ( Boettiger and Doupe, 1998 ; Livingston and Mooney, 1997 ).…”
