This form of inhibitory synaptic areas of the nervous system, excitatory and inhibitory synapses are plasticity declines with age, and we have hypothesized that it reconfigured during early development.

To examine inhibitory synaptic depression, MNTB-evoked maximumamplitude inhibitory postsynaptic potentials (IPSPs) were first ac-quired during a 15-min baseline period initially every minute for thefirst 5 min and then at the 10th and 15th min (Kotak and Sanes 2000).
The MNTB was then activated with low-frequency stimulation (LFS:1 Hz for 15 min). Immediately following LFS, MNTB-evoked IPSPswere recorded every min for the first 5 min and every 5 min thereafter.
To block GABA receptors, SCH-50911 (5–10 ␮M, Tocris) was bath-applied throughout the experiment beginning 5 min before re-cording the first IPSP.
In a separate set of experiments, IPSPs were recorded for about 1 h at a very low rate of acquisition that does not produce synapticdepression (0.03 Hz), and the slices were exposed to either a GABABreceptor agonist (baclofen, 100 ␮M, Sigma Chemicals), or a neuro-trophin [brain derived neurotrophic factor (BDNF), 50 –100 ng/ml,Sigma Chemicals or Alamone Laboratories; NT-3, 25–50 ng/ml,Sigma Chemicals]. In many of these experiments, contaminatingglutamatergic activity was blocked with 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX; 20 ␮M) or kynurenic acid (4 mM). This was donefor control LFS experiments (n ϭ 3), baclofen exposure (n ϭ 2),BDNF exposure (n ϭ 7), NT-3 exposure (n ϭ 6), and SCH-50911treatment (n ϭ 3).
Data were collected using a Macintosh PPC running a custom- designed IGOR (WaveMetrics, v3.14) macro called SLICE. The datawere analyzed off-line using a second IGOR macro called SLICEANALYSIS.

In the gerbil LSO, inter-aural level difference coding improves with age, and severalanatomical and physiological properties are disrupted by deaf-ferentation during development (Sanes et al. 2000b). We havepreviously shown that inhibitory projections from MNTB toLSO become refined during development, and this process isdisrupted by deafferentation (Sanes and Siverls 1991; Sanesand Taka´cs 1993). More recently, we have found that thestrength of these inhibitory synapses depends on activity, andthis phenomenon wanes with age (Kotak and Sanes 2000).

B: the bar graph compares thepercent change in the normalized IPSP amplitude during a control period, a15-min drug exposure period, and after a recovery period. There was asignificant decline (asterisk) in IPSP amplitudes during baclofen treatment, andthis depression persisted at 30 min after the last baclofen exposure. The changein IPSPs was calculated by comparing the average normalized IPSP amplituderecorded during baclofen exposure and at 50 – 60 min of the experiments withthe initial IPSP amplitude (0%) during 1st 10 min of the recording session(comparison between initial IPSPs and IPSPs during baclofen exposure: t ϭ4.01, df ϭ 6, P Ͻ 0.007; comparison between initial IPSPs and IPSPs at 50 – 60min: t ϭ 4.08, df ϭ 6, P Ͻ 0.006).

Approximately 10 min after BDNF application, IPSP ampli-tudes declined, and this attenuation reached its maximum byabout 20 –30 min following drug exposure, but the change didnot reach significance (comparison between initial IPSPs andIPSPs during BDNF exposure: t ϭ 0.36, df ϭ 18, P ϭ 0.72;comparison between initial IPSPs and IPSPs at 50 – 60 min: t ϭ0.17, df ϭ 14, P ϭ 0.07). Exposure to NT-3 (25–50 ng/ml)produced a larger and more rapid decline in IPSP amplitude,and this decline was highly significant (Fig. 3). Finally, toassess whether neurotrophin receptors could influence synap-tically evoked depression, a tyrosine kinase antagonist (200nM K-252a) was added to the internal patch solution.
