“…It has been suggested that the archistriatum of the telencephalon in birds is at least partly comparable to the mammalian amygdala (Edinger et al, 1903;Edinger, 1908;Ariëns-Kappers, 1922;Ariëns-Kappers et al, 1936;Zeier and Karten, 1971;Bruce and Neary, 1995;Puelles et al, 2000), a structure that itself possesses both pallial and subpallial parts (Swanson and Petrovich, 1998;Puelles et al, 2000). Based on neurochemical and developmental data, it seemed overwhelmingly clear to the Forum that all parts of the archistriatum (i.e., the regions with the word archistriatum in their name) as defined in Karten and Hodos (1967) and in Kuenzel and Masson (1988) are pallial Wada et al, 2001, Reiner et al, 2002Sun et al, 2003). The Forum further concluded that the taenia (also called the nucleus taeniae) has typically been regarded as a part of the archistriatal complex, although this was not reflected in its name (Ariëns-Kappers et al, 1936;Zeier and Karten, 1971;Thompson et al, 1998;Chen et al, 1999;Absil et al, 2002) and that much or all of the taenia is subpallial (Foidart et al, 1999;Cobos et al, 2001b;Absil et al, 2002).…”

The standard nomenclature that has been used for many telencephalic and related brainstem structures in birds is based on flawed assumptions of homology to mammals. In particular, the outdated terminology implies that most of the avian telencephalon is a hypertrophied basal ganglia, when it is now clear that most of the avian telencephalon is neurochemically, hodologically, and functionally comparable to the mammalian neocortex, claustrum, and pallial amygdala (all of which derive from the pallial sector of the developing telencephalon). Recognizing that this promotes misunderstanding of the functional organization of avian brains and their evolutionary relationship to mammalian brains, avian brain specialists began discussions to rectify this problem, culminating in the Avian Brain Nomenclature Forum held at Duke University in July 2002, which approved a new terminology for avian telencephalon and some allied brainstem cell groups. Details of this new terminology are presented here, as is a rationale for each name change and evidence for any homologies implied by the new names.Revisions for the brainstem focused on vocal control, catecholaminergic, cholinergic, and basal ganglia-related nuclei. For example, the Forum recognized that the hypoglossal nucleus had been incorrectly identified as the nucleus intermedius in the Karten and Hodos (1967) pigeon brain atlas, and what was identified as the hypoglossal nucleus in that atlas should instead be called the supraspinal nucleus. The locus ceruleus of this and other avian atlases was noted to consist of a caudal noradrenergic part homologous to the mammalian locus coeruleus and a rostral region corresponding to the mammalian A8 dopaminergic cell group. The midbrain dopaminergic cell group in birds known as the nucleus tegmenti pedunculopontinus pars compacta was recognized as homologous to the mammalian substantia nigra pars compacta and was renamed accordingly; a group of ␥-aminobutyric acid (GABA)ergic neurons at the lateral edge of this region was identified as homologous to the mammalian substantia nigra pars reticulata and was also renamed accordingly. A field of cholinergic neurons in the rostral avian hindbrain was named the nucleus pedunculopontinus tegmenti, whereas the anterior nucleus of the ansa lenticularis in the avian diencephalon was renamed the subthalamic nucleus, both for their evident mammalian homologues.For the basal (i.e., subpallial) telencephalon, the actual parts of the basal ganglia were given names reflecting their now evident homologues. For example, the lobus parolfactorius and paleostriatum augmentatum were acknowledged to make up the dorsal subdivision of the striatal part of the basal ganglia and were renamed as the medial and lateral striatum. The paleostriatum primitivum was recognized as homologous to the mammalian globus pallidus and renamed as such. Additionally, the rostroventral part of what was called the lobus parolfactorius was acknowledged as comparable to the mammalian nucleus accumbens, which, together with the...

Dysfunction of hippocampal interneurons in epilepsy

Gamma-amino-butyric acid (GABA)-containing interneurons are crucial to both development and function of the brain. Down-regulation of GABAergic inhibition may result in the generation of epileptiform activity. Loss, axonal sprouting, and dysfunction of interneurons are regarded as mechanisms involved in epileptogenesis. Recent evidence suggests that network connectivity and the properties of interneurons are responsible for excitatory-inhibitory neuronal circuits. The balance between excitation and inhibition in CA1 neuronal circuitry is considerably altered during epileptic changes. This review discusses interneuron diversity, the causes of interneuron dysfunction in epilepsy, and the possibility of using GABAergic neuronal progenitors for the treatment of epilepsy.

“…In the chick, GABAergic neurons generate in the subpallium and migrate tangentially into the pallium (Cobos et al, 2001;Tuorto et al, 2003). In the adult chicken, glutamic acid decarboxylase 65 mRNA, which synthesizes GABA, is expressed in the subpallium, including the striatum, globus pallidus, interpeduncular nucleus, nucleus accumbens, lateral part of the bed nucleus of the stria terminalis, subpallial amygdaloid area, and septum (Sun et al, 2005). In contrast, the present study clearly showed that VGLUT2 mRNA is expressed extensively in the pallial structures of the pigeon, i.e., the hyperpallium, mesopallium, nidopallium, hippocampal formation, dorsolateral corticoid area, temporo-parieto-occipital area, piriform cortex, arcopallium, posterior pallial amygdala, and nucleus taeniae of the amygdala.…”

Glutamate acts as the excitatory neurotransmitter in the central nervous system (CNS) and is mediated largely by the vesicular glutamate transporters (VGLUT1-3) and alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) types of glutamate receptors (GluR1-4) in mammals. In the present study, we determined the cDNA sequences of pigeon VGLUT2 and GluR1 and mapped the distribution of their mRNA in the pigeon CNS. The predicted amino acids of pigeon VGLUT2 and GluR1 showed a 93% identity to human VGLUT2 and GluR1 both. In situ hybridization autoradiograms showed VGLUT2 mRNA expression exclusively in the pallium of the telencephalon, and no expression in the subpallium. Within the diencephalon, VGLUT2 mRNA was more abundant in the thalamus than in the hypothalamus. Rich VGLUT2 mRNA expression was found in the optic tectum, nucleus mesencephalicus lateralis, pars dorsalis, nucleus isthmi, pars parvocellularis, isthmo-optic nucleus, pontine nuclei, and granular layer of the cerebellum. Moderate expression was noted in the cerebellar nuclei, vestibular nuclei, cochlear nuclei, inferior olivary nucleus, and gray matter of the spinal cord. GluR1 mRNA was expressed abundantly in the pallium and subpallium of the telencephalon, but it was poor in the diencephalon, midbrain, medulla, cerebellar cortex, and gray matter of the spinal cord. These results suggest that the cDNA sequences of VGLUT2 and GluR1 in the pigeon are comparable to those of VGLUT2 and GluR1 in mammals, respectively. The distribution of pigeon GluR1 mRNA resembles that of mammals, but the distribution of VGLUT2 mRNA resembles that of both VGLUT1 and VGLUT2 in mammals.
