“…The nucleus accumbens and adjacent ventral putamen, referred to as the ventral or limbic striatum, exhibit the highest expression of D 3 receptor binding sites and corresponding levels of D 3 mRNA. These regions are the targets of the mesolimbic DA system receiving input from the medial and dorsal components of the SN (Jimenez-Castellanos and Graybiel 1987;Lynd-Balta and Haber 1994a;Haber and Fudge 1997). Additional sources of input to the limbic striatum include regions enriched in D 3 receptors such as the anterior nuclei of the thalamus and NBM.…”

“…To retain the abbreviation HD, the Forum approved the term hyperpallium densocellulare (Table 3, Figs 6D, 7A, 8A,B). The adjective "densocellular" has been used previously in the neuroanatomical literature (e.g., Jiminez-Castellanos and Graybiel, 1987;Popken et al, 2000;Fudge and Haber, 2001), and it appropriately describes the HD, because it stands out as cell dense in Nissl-stained material (Karten and Hodos, 1967).…”

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 In particular, the outdated terminology implies that most of the avian telencephalon is a hypertrophied basal ganglia, when it is now clear that most of the avian telencephalon is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...

“…The axons of DA neurons emerge from a proximal dendrite and project to the striatal complex in a roughly topographical manner [85][86][87][88]. All DA neurons innervate both the striosome (also called patch) and matrix compartments of the striatum, although the axonal arborization of dorsal tier neurons favour the matrix, whereas ventral tier neurons tend to favour striosomes [10,86,89,90]. Within these populations, additional biochemical and physiological differences confer differential excitability, as well as differential vulnerability to pathophysiological insults [88,91 -94], with greater susceptibility of ventral tier neurons of the SNc to degeneration in PD (and animal models of the disease) than those in the dorsal tier of SNc or the VTA [95,96].…”

One contribution of 16 to a discussion meeting issue 'Release of chemical transmitters from cell bodies and dendrites of nerve cells'. Dopamine (DA) is a key transmitter in motor, reward and cogitative pathways, with DA dysfunction implicated in disorders including Parkinson's disease and addiction. Located in midbrain, DA neurons of the substantia nigra pars compacta project via the medial forebrain bundle to the dorsal striatum (caudate putamen), and DA neurons in the adjacent ventral tegmental area project to the ventral striatum (nucleus accumbens) and prefrontal cortex. In addition to classical vesicular release from axons, midbrain DA neurons exhibit DA release from their cell bodies and dendrites. Somatodendritic DA release leads to activation of D2 DA autoreceptors on DA neurons that inhibit their firing via G-protein-coupled inwardly rectifying K þ channels. This helps determine patterns of DA signalling at distant axonal release sites. Somatodendritically released DA also acts via volume transmission to extrasynaptic receptors that modulate local transmitter release and neuronal activity in the midbrain. Thus, somatodendritic release is a pivotal intrinsic feature of DA neurons that must be well defined in order to fully understand the physiology and pathophysiology of DA pathways. Here, we review recent mechanistic aspects of somatodendritic DA release, with particular emphasis on the Ca 2þ dependence of release and the potential role of exocytotic proteins.
