Inhibitory Action of the Amygdala on the Lateral Hypothalamic Area in Rats
Nature, 1970THE mammalian lateral hypothalamic area (LH) and the ventromedial hypothalamic nucleus (VMH) are involved in feeding and satiety function, respectively1. There is also reciprocity of electrical activity between the two2. Anatomically related to these areas, the amygdala has been shown to be involved in the same functions.

Molecular Mechanisms of Threat Learning in the Lateral Nucleus of the Amygdala
2014Pavlovian threat conditioning is a behavioral paradigm that has been successfully utilized to define the mechanisms underlying threat (fear) memory formation. The amygdala is a temporal lobe structure required for the acquisition, consolidation, and expression of threat (fear) memories.

Mechanism of inhibition by the amygdala in the lateral hypothalamic area of rats
Brain Research Bulletin, 1982The inhibition of neuronal activity in the lateral hypothalamus (LHA) of the rat by the basolateral nucleus of the amygdala (AL) was investigated by analyzing evoked potentials, single unit discharges and intracellular synaptic potentials. A single volley to the AL induced a negative-positive-wave in the LHA.

Functional relationship of lateral hypothalamus and amygdala in control of eating
Pharmacology Biochemistry and Behavior, 1975Cannulas were stereotactically implanted in the lateral hypothalamus and the ipsilateral amygdaloid cortical nucleus of 7 male albino rats, Wistar strain. After functional checking of the accuracy of implants by adrenergic elicitation of increased food intake, the animals were injected with combinations of noradrenaline, phenoxybenzamine or tolazoline,

Laterality of dopamine function and neuroleptic action in the amygdala in the rat
Neuropharmacology, 1985Rats selected according to turn preference in an open field were categorised as showing left or right hemispheric dominance (turning to right or left respectively). Dopamine was persistently infused into the central area of the left or right amygdala of animals showing left or right hemispheric dominance.

Parvalbumin interneurons constrain the size of the lateral amygdala engram
Neurobiology of Learning and Memory, 2016Memories are thought to be represented by discrete physiological changes in the brain, collectively referred to as an engram, that allow patterns of activity present during learning to be reactivated in the future. During the formation of a conditioned fear memory, a subset of principal (excitatory) neurons in the lateral amygdala (LA) are allocated to

Lateral hypothalamic dynorphinergic efferents to the amygdala and brainstem in the rat
Peptides, 1988Dynorphin is present within perikarya of the lateral hypothalamus (LH) and perifornical nucleus (PeF), and within nerve terminals of the central nucleus of the amygdala, central grey, parabrachial nucleus, and the dorsal vagal complex (nucleus of the solitary tract and dorsal motor nucleus of the vagus).

Spike doublets in neurons of the lateral amygdala
NeuroReport, 2000A majority of projection neurons in the lateral amygdala generate oscillatory spike firing in the theta-frequency range, largely due to intrinsic membrane properties. Here we report on the occurrence of spike doublets in about 70% of these cells. Spike doublets consisted of a fast initial and a second slower component, which were mediated by sodium ...

Increased concentrations and lateral asymmetry of amygdala dopamine in schizophrenia
Nature, 1983There is a growing body of evidence in support of the view of schizophrenia as a dysfunction of the left temporal lobe. This hypothesis, first proposed by Flor-Henry, stemmed from the frequently observed association of schizophreniform psychoses with left-sided temporal lobe epilepsy.

Kindling of the lateral septum and the amygdala: Effects on anxiety in rats
Physiology & Behavior, 2011Long-term kindling of limbic system structures may produce substantial changes in emotional behavior in rats. This study examined long-term changes in two kindled structures that have opposite effects on anxiety, the lateral septum and the central nucleus of the amygdala.
