Efferent connections of the caudal part of the globus pallidus in the rat
The efferent connections of the caudal pole of the globus pallidus (GP) were examined in the rat by employing the anterograde axonal transport of Phaseolus vulgaris leucoagglutinin (PHA‐L), and the

The nigrostriatal component, as expected, is the greatest but numerous cells of the mesencephalic raphe system also project to the striatum, and the projections from the pars compacta are organized in a topographical manner in all principal planes.
Topographic organization of the brainstem afferents to the mediodorsal thalamic nucleus
The findings show the MD as a thalamic link of three different groups of brainstem structures projecting to different cortical areas with different functional significance.
The distribution of the projection from the parataenial nucleus of the thalamus to the nucleus accumbens in the rat: An autoradiographic study
It is suggested that the parataenial nucleus is an important thalamic link between limbic and striatal processing and there is a nearly complete overlap between the parATAenial afferents and those coming from hippocampus.
Thalamoamygdaloid projections in the rat: A test of the amygdala's role in sensory processing
The results show that, like the cortical amygdaloid nuclei, which are sensory (olfactory) in nature, the subcortical amygdAloiduclei must have major sensory functions.


Convergent thalamic and mesencephalic projections to the anterior medial cortex in the rat
HRP injected into the medial cortex of five rats pre‐treated with 6‐hydroxydopamine, a drug that produces chemical lesions of catecholamine neurons, failed to label any cells in AVT and SNC but did label numerous cells in MD and AM, suggesting that the ventral tegmental cells projecting to the anterior medial cortex are exclusively dopamine neurons.
Nigrostriatal and nigrothalamic fibers in the rhesus monkey
Lesions in caudal parts of the substantia nigra (SN) produced in 11 monkeys were localized to lateral, medial and central regions and the location of degeneration in the putamen appeared related to the part of the SN destroyed.
Ascending projections of the substantia nigra in the rat ,
The demonstration of projections from the cerebellum and substantia nigra to VM establishes this nucleus as the homologue in the rat of nuclei ventralis anterior and ventral is lateralis lateralis thalami in primates.
Catecholamine innervation of the basal forebrain IV. Topography of the dopamine projection to the basal forebrain and neostriatum
The topography of the DA neuron projection on the basal forebrain and neostriatum is organized in three planes, dorsal‐ventral, medial‐lateral and anterior‐posterior, consistent with the view that the DA neurons of the SN‐VTA complex form a single nuclear group with a highly topographically organized projection innervating not only deep nuclei of the telencephalon but allocortical structures as well.

The ascending monoamine pathways in the rat brain are demonstrated by the pile up of fluorescent material occurring in the axons after various types of lesions, indicating a unique role for the locus coeruleus in influencing the activity of the entire brain.
The connections of the nucleus reuniens thalami: Evidence for a direct thalamo‐hippocampal pathway in the rat
The afferent and efferent connections of the rat's midline nucleus reunions thalami (reuniens) were studied by experiments using the methods of retrograde cell marking by horseradish peroxidase and anterograde fiber tracing by autoradiography to provide the first evidence of a direct thalamo‐hippocampal connection.
The adrenergic innervation of the rat thalamus as revealed by the glyoxylic acid fluorescence method
Many areas of the thalamus and adjoining regions, that appear sparsely innervated by catecholamine (CA) fibers in specimens processed according to the standard Falck‐Hillarp formaldehyde method, were found to be richly supplied with such fibres in the glyoxylic acid‐treated specimens.
