Anatomical and Functional Mapping of the Auditory Corticostriatal Projection
(A) Fluorescence image showing the ACx injection site and retrograde labeling in the medial geniculate nucleus (MG). Scale bar, 25 μm.
(B) Fluorescence image of a coronal slice showing dense anterograde labeling from the ACx to the dorsolateral striatum. Scale bar, 1 mm; inset, 25 μm.
(C) Fluorescence image of a coronal slice containing sparse ACx labeling within the dorsomedial striatum. Scale bar, 1 mm; inset, 25 μm.
(D) Scatterplot showing the percentage of total area within the striatum labeled by ACx injections (y axis) as a function of distance from the rostral pole of the hippocampus (x axis).
(E) Diagram showing the ACx site of AAV injection and the plane of the slice preparation containing the injection site.
(F) Schematic of the corticostriatal slice preparation with the ACx L5/6 injection site and labeled pathways.
(G) Fluorescence image showing ACx L5/6 injection site and labeling in the MG but no labeling in the lateral geniculate nucleus (LG).
(H) Fluorescence image showing anterograde labeled fibers of passage and terminals from L5 pyramidal neurons synapsing onto striatal neurons (inset).
(I) Diagram showing the slice preparation and experimental design for evoking PSPs in striatal neurons.
(J) Micrograph showing the region of the striatum used for functional mapping. Numbers represent the site of a patched neuron and are accompanied by traces of PSPs following stimulation of L5.
(K) Micrograph showing the approximate mediolateral-rostrocaudal location of recorded striatal neurons used for functional mapping and the peak amplitude of the PSP for each cell (colored bar, left).
(L) A scatter diagram showing the peak PSP amplitude as a function of distance from the rostral pole of the hippocampus.

The Effect of Transient Developmental HL on Cortical and Striatal Intrinsic Properties
(A) Diagram illustrating the experimental design (top), and examples of a recorded L5 pyramidal neuron (bottom left) and a recorded medium spiny neuron (bottom right) filled with fluorescent biotin.
(B) Bar graph showing the average resting membrane potential in control (Ctl) and HL animals for L5 pyramidal neurons (L5, orange) and striatal MSNs (Str, green).
(C) Bar graph showing the average membrane resistance in response to a −30 pA current pulse in control and HL animals for L5 pyramidal neurons and striatal MSNs.
(D) Representative traces are shown for a Ctl and an HL L5 neuron in response to depolarizing and hyperpolarizing current pulses (left). The plot compares the average input-output functions for ACx L5 neurons in Ctl and HL animals. The Ctl:HL ratio of the maximum firing rate at an injected current level of 600 pA was 0.94 (dashed box).
(E) Representative traces are shown for a Ctl and an HL striatal MSN in response to depolarizing and hyperpolarizing current pulses (left). The plot compares the average input-output functions for striatal MSNs in Ctl and HL animals. The Ctl:HL ratio of the maximum firing rate at an injected current level of 600 pA was 0.51 (dashed box).
Data are represented as mean ± SEM. ∗∗p < 0.01.

The Effect of Transient Developmental HL on Cortical and Striatal Inhibitory Gain
(A) Representative traces showing L5 (top, orange) and striatal (bottom, green) sIPSCs from Ctl and HL animals. The bar graph shows average sIPSC amplitude in Ctl and HL animals for ACx L5 and striatal MSNs.
(B) Representative traces showing L5 (top, orange) and striatal (bottom, green) me-IPSCs. The bar graph shows average me-IPSC amplitude in Ctl and HL animals for ACx L5 and striatal MSNs.
(C) Representative traces showing L5 (top, orange) and striatal (bottom, green) evoked IPSCs at 2× the threshold stimulus current. The bar graph shows average IPSC amplitude in Ctl and HL animals for ACx L5 and striatal MSNs. We computed the Ctl:HL ratio of evoked IPSC amplitude. The value was 2.8 for L5 neurons and 0.52 for striatal MSNs (dashed boxes).

The Effect of Developmental HL on Cortical and Striatal Excitatory Properties
(A) Diagram showing the experimental design for recording light-evoked EPSPs.
