| state-dependent learning | Learning during a specific state of sleep or wakefulness, or during a chemically altered state, where retrieval of learned information (e.g., as measured by performance of a learned response) cannot be demonstrated unless the subject is restored to the state that originally existed during learning.

| steady state | A dynamic equilibrium. (13 Nov 1997) |
| steady-state rate | The velocity of an enzyme-catalyzed reaction in which, over the time course of the study, the concentration of any enzyme species is constant (i.e., for an enzyme-substrate binary complex, ES, d[ES]/dt&apprxeq;00; for this to hold true, the total enzyme concentration must be much less than the initial substrate concentration. Synonym: steady-state rate. (05 Mar 2000) |

| decerebrate state | A peculiar neurologic condition elicited in vertebrates as a consequence of the elimination of brain function by transecting the brainstem or interrupting function by other techniques. Clinically, brain damage can result in neurological signs resembling those of a decerebrate animal. The state consists of exaggerated postures, grossly abnormal reflexes, convulsions, and extreme muscular rigidity and spasticity. (12 Dec 1998) |
| decorticate state | A unilateral or bilateral postural change, consisting of the upper extremities flexed and adducted and the lower extremities in rigid extension; due to structural lesions of the thalamus, internal capsule, or cerebral white matter. Synonym: decorticate state. (05 Mar 2000) |
| dreamy state | The saemiconscious state associated with an epileptic attack. Synonym: absent state. (05 Mar 2000) |
| imperfect state | In fungi, the state or stage at which only asexual spores such as conidia are formed; most such species are classified as Deuteromycetes (Fungi Imperfecti). (05 Mar 2000) |
