Texture Identification by Bounded Integration of Sensory Cortical Signals
Recent work demonstrated that when a rat palpates a surface to identify its texture, signals generated by whisker kinematics are integrated by the brain, one touch at a time, until the accumulated evidence supports a well-grounded choice. The framework of decision making through bounded integration, previously attributed to primates, thus extends to rodents. In the present study, we ask whether vibrissal somatosensory cortex (vS1 and vS2) functions as the integrator of incoming evidence or, alternatively, as a relay of evidence to a downstream integrator. Rats carried out 1–6 touches per trial to discriminate among candidate textures. We calculated the evidence for each texture, per touch, carried by the firing rates of sets of neurons in vS1 and vS2. The quantity of information within vS1 and vS2 did not grow progressively; instead, the decision was accounted for by modeling a downstream integrator that accumulated packets of vS1 and vS2 texture information until the total quantity of evidence for one texture reached a boundary. In this behavioral task, vibrissal somatosensory cortex appears to act as a sensory relay. Bounded integration is likely to take place in regions targeted by somatosensory cortex. When a rat palpates a surface to identify texture, vibrissal kinematic evidence is integrated by the brain one touch at a time. In this study, Zuo and Diamond find that vibrissal somatosensory cortex (vS1 and vS2) acts as a touch-by-touch distributor of evidence to a downstream integrator, where accumulation to a boundary triggers the decision
Rats Generate Vibrissal Sensory Evidence until Boundary Crossing Triggers a Decision
Behaviors in which primates collect externally generated streams of sensory evidence, such as judgment of random dot motion direction, are explained by a bounded integration decision model. Does this model extend to rodents, and does it account for behavior in which the motor system generates evidence through interactions with the environment? In this study, rats palpated surfaces to identify the texture before them, showing marked trial-to-trial variability in the number of touches prior to expressing their choice. By high-speed video, we tracked whisker kinematic features and characterized how they encoded the contacted texture. Next, we quantified the evidence for each candidate texture transmitted on each touch by the specified whisker kinematic features. The instant of choice was well fit by modeling the brain as an integrator that gives the greatest weight to vibrissal evidence on first touch and exponentially less weight to evidence on successive touches; according to this model, the rat makes a decision when the accumulated quantity of evidence for one texture reaches a boundary. In summary, evidence appears to be accumulated within the brain until sufficient to support a well-grounded choice. These findings extend the framework of bounded sensory integration from primates to rodents and from passively received evidence to evidence that is actively generated by the sensorimotor system. Faced with uncertain sensory inputs, primates integrate evidence over time to a decision boundary. Zuo and Diamond ask whether rats’ employ bounded integration as they generate tactile evidence to identify texture. On each trial, rats accumulate vibrissal signals across touches; they make a decision when the integrated quantity reaches a boundary
Dryopteris sukungiana Z. Y. Zuo 2022, sp. nov.
Dryopteris sukungiana Z. Y. Zuo, sp. nov. (Figs. 1 & 2), in Chinese 云Dzfl毛ƃ (yún nán lín máo jué). Type:— CHINA. Yunnan: Maguan, 103°59’ E / 22°50’ N, 1950 m alt., 22 June 2021, Z. Y. Zuo 4660 (holotype KUN-1519949; isotypes HITBC-0061304, KUN-1519950, PE-02354809). Diagnosis:— The scales of Dryopteris sukungiana are blackish brown and spreading (Fig. 3E), which is different from all other species in the D. sparsa complex (Fig. 3D, 3F). Dryopteris sukungiana is similar to the ‘typical’ Sino-Himalayan D. sparsa with erect rhizomes, deltoid or pentagonal tripinnatifid to tripinnate lamina, basal pinnae abruptly broadened toward the base (Fig. 3A, 3B), but differs in having glandular hairs and small fibrillose scales on the abaxial surface of the lamina and the indusia (Fig. 3G, 3H). It resembles the Sino-Japanese D. sparsa in the catadromous pinnules of the second pair of pinnae and glandular hairs on the indusia and the abaxial surface of the lamina (Fig. 3H, 3I); however, the lamina of the Sino-Japanese D. sparsa is ovate-deltoid, and the basal pinnae are gradually broadened (Fig. 3C). Dryopteris sukungiana also looks like D. angustipalea Darnaedi, M. Kato & K. Iwats. (1989a: 308); however, the latter is endemic to Indonesia, and in which the lamina is ovate-deltoid, the basal pinnae are gradually broadened toward the base, rachis and costae are glabrous. Plants 30–60 cm tall. Rhizome erect, up to 8 cm long and 2 cm in diameter, clothed with blackish brown, linear- or ovate-lanceolate, spreading, entire scales. Stipe slightly shorter than lamina, ca. 17–38 cm, covered with glandular hairs when young, brown at base, with blackish brown linear- or ovate-lanceolate, spreading, entire, scales. Lamina papery, glossy, deltoid or pentagonal, ca. 26–53 × 18–35 cm, tripinnatifid to tripinnate, base not narrowed, apex acuminate, with glandular hairs on abaxial surface. Pinnae 9–17 pairs, deltate-lanceolate, up to 16 × 6 cm, apex caudate-acuminate; Basal 1–3 pairs opposite and alternate upward, oblique, stalked approximately 1–2 cm. Basal pinnae abruptly broadened toward the base. Pinnules 9–23 pairs, margin serrate to lobed, opposite at base and alternate upward, lanceolate to rounded, base broadly cuneate, asymmetrical, apex obtuse to truncate. Basal basiscopic pinnules of basal pinnae longest, ca. 5–8 × 2–3 cm, base widest, 2-pinnate. Pinnules of the second pair of pinnae catadromous. Rachis and costa clothed with glandular hairs and small fibrillose scales. Veins pinnate, forked, distinct on both surfaces. Sori close to costa on pinnules, with a wide sterile belt on both sides of costa distal to sori. Indusia orbicularreniform, entire, with glandular hairs. Reproductive mode and ploidy level: sexual tetraploid. Additional specimens examined (paratypes): — CHINA. Yunnan: Baoshan, Z. Y. Zuo 1615 & 4937; Cangyuan, Z. Y. Zuo 2862; Kunming, J. M. Lu 179; Longling, X. Cheng et al., FB581; Tengchong, Z. Y. Zuo 1498, 1520 & 4949. Ecology and geographical distribution: — Dryopteris sukungiana was found in mountain forests at alt. 1900‒ 2450 m in the central, southern, and southwestern parts of Yunnan Province, China, and perhaps in other neighboring areas. Etymology:— In honor of late Prof. Su-Gong Wu (Su-Kung Wu in Wide-Giles transliteration) (1935-2013), for his contributions to the taxonomic studies on ferns in China, and especially the contributions to collections and studies on the ferns of the Qinghai-Tibet Plateau.
