TL;DR
Extracellular unit recordings were obtained from the prefrontal cortex of free-moving cats with the head fixed and the prevailing effect produced by electrical stimulation of dorsal amygdala (AD) and N. medialis dorsalis thalami (DM) was a decrease in the spontaneous activity of CPF neurons.
Abstract
Extracellular unit recordings were obtained from the prefrontal cortex (CPF) of free-moving cats with the head fixed. The prevailing effect produced by electrical stimulation of dorsal amygdala (AD) and N. medialis dorsalis thalami (DM) was a decrease in the spontaneous activity of CPF neurons, while lateral hypothalamus (HL) stimulation produced an increase. Concurrent electrical stimulation of HL and DM, and HL and AD produces suppression of the effect induced by HL single stimulation. Basal amygdala (AB) and DM simultaneous stimulation produces suppression of DM single stimulation.

The Journal of Comparative NeurologyThe cortical projections of the mediodorsal nucleus and adjacent thalamic nuclei in the rat
1,267 Citations1977J. E. Krettek, Joseph L. Price
The mediodorsal nucleus of the rat thalamus has been divided into medial, central and lateral segments, and these segments have been shown by experiments using the autoradiographic method of demonstrating axonal connections to project to seven distinct cortical areas covering most of the frontal pole of the hemisphere.

401 Citations1972B Kaada
It is shown that stimulation and ablation of the amygdaloid nuclear complex result in a variety of somatic, visceral, endocrine and behavioral effects, and attempts have been made to correlate structure and patterns of responses.
Neuroscience LettersSubcortical afferents of the amygdaloid complex in the rat: an HRP study
238 Citations1978Jan G. Veening
Small unilateral deposits of horseradish peroxidase (HRP) were delivered into the various nuclei of the amygdaloid complex in 44 rats, and retrogradely labeled neurons were observed in thalamus, hypothalamus, and brain stem.

This paper is the result of a series of experiments performed in an attempt to determine the wider neural organizations of which the amygdaloid complex forms a part.

221 Citations1975J. Kievit, H.G.J.M. Kuypers
In the rhesus monkey, retrogradely labeled neurons, containing HRP reaction granules in the cell body and proximal parts of the dendrites, were present in the thalamus as well as in the substantia innominata and the hypothalamus and the latter areas will be referred to as the basal forebrain areas.

The connections of the mediodorsal nucleus were compared in rats, cats and monkeys and the paralamellar portion received from the cerebellum, superior colliculus and spinal cord and projects to the medial frontal area in rats and area 8 in monkeys.

Inputs to rat lateral hypothalamus from prefrontal cortex (FC), and vice versa, were studied by intracellular recording, and by retrograde horseradish peroxidase (HRP) method.
Experimental NeurologyElectroencephalographic, behavioral, and single-unit effects produced by stimulation of forebrain inhibitory structures in cats
71 Citations1974Jerome H. Siegel, Rex Y. Wang
The data indicate that the three forebrain inhibitory regions have a convergence of synchronizing influences and that these influences are exerted upon cells sampled from all structures explored, which suggests that the forebrain-influencing pathways are fairly direct rather than circuitous.

These findings confirm the functional independence of dorsolateral and orbital frontal cortex and suggest that characterizing the behavioral changes following orbital lesions as either perseveration or disinhibition is not entirely accurate.
Experimental NeurologyThe pathway from the mediodorsal nucleus of thalamus to the hypothalamus in the cat
24 Citations1973Allan Siegel, Henry Edinger +1 more
The findings suggest the existence of a fine-caliber fiber system from the anterior midline thalamus to the hypothalamus, and indicate a multisynaptic circuit from the mediodorsal nucleus of the thalamic mediodor nucleus tothe hypothalamus.

18 Citations1980Hans J. Markowitsch, Monika Pritzel +1 more
Cat brains with cortical injections of horseradish peroxidase resulting in labelled cells in the thalamic mediodorsal nucleus (MD) were screened for afferent projections from the parietal cortex, revealing possible differences in the parieto-prefrontal organization of both species.

The HRP technique has in fact revealed the existence of direct connections ascending from various hypothalamic regions, s and amygdaloid nuclei lz to sensorimotor cortical neurons in cats, and the aim of this investigation has been to study any postsynaptic changes in sensorim motor cortical neurons during hypothalamic and amyghaloid stimulation.

Development of rat-killer behaviour by environmental factors was observed in two cats, however, food deprivation never converted a non-killer into a killer cat.
