The claustral projections to the cat's limbic cortex were investigated with horseradish peroxidase retrograde tracing technique and with autoradiography. Autoradiographic injections covered small portions of either the dorsal anterior claustrum or intermediate to posterior regions of the claustrum. Injections of horseradish peroxidase were made into the subicular, insular, entorhinal, prepiriform, cingulate, retrosplenial and prefrontal cortex. Both methods revealed fully consistent data for… 
Reciprocal connections of the insular and piriform claustrum with limbic cortex: An anatomical study in the cat
TLDR
The present data provide a more differentiated view, such that the ventral portion of the claustrum is reciprocally connected mainly with the olfactory-related cortices and the entorhinal cortex, whereas the cortical connections of progressively more dorsal parts of thecluster gradually shift from limbic and paralimbic towards parasensory and sensory cortical connections.
Interhemispheric connections between the infralimbic and entorhinal cortices: The endopiriform nucleus has limbic connections that parallel the sensory and motor connections of the claustrum
TLDR
An interhemispheric circuit in which IL projects bilaterally to DEn, with the densest terminal labeling appearing in the contralateral hemisphere around retrogradely labeled neurons that project to IL in that hemisphere is revealed.
The organization of the ipsi- and contralateral claustrocortical system in rat with notes on the bilateral claustrocortical projections in cat
TLDR
The intricate organization of the claustral-ascending projections suggests that the nucleus is involved in different cortical activities and that its efferents may also provide the substrate of a powerful subcortical mechanism of interhemispheric communication.
Basal forebrain efferents reach the whole cerebral cortex of the cat
TLDR
A widespread innervation of the cat's cerebral cortex by the basal forebrain is indicated, which has recently been found also in monkeys and rats.
Organization of the claustrum-to-entorhinal cortical connection in mice.
TLDR
Investigation of the organization and function of identified claustro-cortical projections in mice using multiple anatomical and optogenetic techniques suggests that the dense claustra-MEC pathway is activated by novel context and modulates MEC function in contextual memory.
Organization of the Claustrum-to-Entorhinal Cortical Connection in Mice
TLDR
The results suggest that the dense claustro–MEC pathway is activated by novel context and modulates MEC function in contextual memory.
The limbic zone of the rabbit and rat claustrum: a study of the claustrocingulate connections based on the retrograde axonal transport of fluorescent tracers
TLDR
Double-labeling study showed that neurons projecting to various limbic regions are intermingled and that neurons sending axons into two different limbic areas are seen only occasionally, giving support to the role of the claustrum in integrating information between different areas of the cerebral cortex and the limbic system.
Chapter 2 – The Structure and Connections of the Claustrum
The claustrum is a telencephalic, pallial subcortical structure which has been identified in all eutherian and metatherian mammals. It consists of two principal subdivisions: the dorsal or insular
Cortical and subcortical afferent connections of the squirrel monkey's (lateral) premotor cortex: evidence for visual cortical afferents.
TLDR
The afferent connections of the squirrel monkey's lateral premotor cortex were investigated with the horseradish peroxidase (HRP) technique and it was concluded that the (lateral) prem motor cortex is involved in sensorimotor integration to a higher degree than has been recognized up to now.
Cortical connections of the claustrum and subjacent cell groups in the hedgehog tenrec
TLDR
The present connectional study confirms that in the hedgehog tenrec, the claustrum is not located below but between the layers of the rhinal/insular cortex (Künzle and Radtke-Schuller 2000b), and shows that the tenrec’s dorsal claustrums was reciprocally and bilaterally connected with the neocortex.

Following HRP injections into the sensorimotor, association and auditory cortex of the cat HRP positive neurons were found in the dorsal claustrum on the side of the injection and contralaterally, an evidence of uncrossed as well as of crossed claustro-neocortical projections.

TLDR
The cat's dorsocaudal claustrum was studied in Golgi preparations, by electron microscopy, and by anterograde and retrograde tracer techniques, finding the claustrocortical axons terminate in all cortical layers but most heavily in layers IV and VI.
Widespread cortical projections of the hippocampal formation in the cat
TLDR
It is suggested that the projection from the subicular cortex to the neocortical areas of the frontal pole (medial prefrontal cortex) is of special importance as it may constitute a link between the association Areas of the neocortex and those regions of the limbic system thought to play a role in memory.
The organization of the claustroneocortical projections in the cat studied by means of the HRP retrograde axonal transport
TLDR
The projections from the claustrum to the cerebral cortex were examined in the cat by means of horseradish peroxidase (HRP) injections in various different areas of the lateral and medial surfaces of the neocortex and showed a prevalent anteroposterior and dorsoventral topographical arrangement.
Afferent and efferent connections between the claustrum and parietal association cortex in cat: A horseradish peroxidase and autoradiographic study
TLDR
There are three findings: MSA and ALA project to and receive fibers from restricted areas of the dorsal claustrum, suggesting a reciprocal claustral-cortical relationship and the projections are bilateral with the ipsilateral projection predominating.
Cortical and subcortical, including sensory-related, afferents to the thalamic mediodorsal nucleus of the cat.
TLDR
Results show that MD receives afferents from a large variety of structures, among them are several cortical as well as subcortical regions related to the processing of sensory and motor information.

TLDR
It is revealed that the dorsal claustrum of the cat projects to almost entire regions of the bilateral neocortex and that distribution of labeled neurons in the bilateral claustrums has topographical correspondence, rostro-caudal as well as dorso-ventral, with regard to the sites of injections in the neocortex.

TLDR
It appears that some cell groups project to the entire neocortex either evenly (here called the disperse pattern or projection) or so that one area receives a more convergent innervation than others (the preferential pattern).

Physiological and anatomical methods were used to study the representation of the visual field in the cat's dorsocaudal claustrum, finding it to contain a single, orderly map of the contralateral hemifield and a small part of the ipsilateral field.
